Okay, so can you take a look at something for me? Please take a look at the outside connections panel, where it shows your import and export. Are goods showing up on either one (it's the purple color I think)? If you're still importing, then yeah, you probably need to produce more internally. But if you are exporting a significant amount, then you do NOT need more industry. You are making so much that your commercial areas cannot consume it all.
Also, where specifically are you seeing that your commercial areas are demanding more goods? I had talked about the RCI meters but you said it didn't have to do with that. What is specifically telling you that you need to produce more goods? You also said something about a mod that was recalculating something for you. Which mod is this?
Do you use the industries DLC by any chance? I know that income from that can fluctuate quite a bit.
As for the tidal wave, only thing I know that could cause that without disasters is if some landscaping was done near a water source. Modifying the terrain height near or in the water can disturb it enough that it needs time to settle down. Note that you don't have to be near the coast for this to happen. If you have a lake or even a small pond, it can happen there, too. Any body of water you see in the game has a water source in it.
And again, it would really help us help you if you posted some screenshots of what you are seeing.
OK this thread is branching out to multiple topics so I'll address each in turn, but before I do I want to make something clear. I'm inexperienced, not a raw noob. I have a decent grasp of the game mechanics at this point, it's the experience with the game mechanics I lack, the little tricks more experienced builders use to keep things ticking over nicely. Keep that when you approach this, please.
So Industry, yes I use Industries DLC (I have all purchasable content for this game). I'm importing around twice as much as I'm exporting and by some ridiculous margin, Goods is the highest percentage of imports. Ten times as many Goods are imported as I export. After that everything else is fairly balanced because my specialised industries are set up in a way to only service my unique factories and not export their wares which, before the problem started, allowed me to engage in a minimalist approach which massively increased profits.
Here is a before and after of my loss of income. The change is the addition of a new downtown area that is comprised mostly of offices with a few residential thrown in, and some commercial around the fringes. The redesign of my low density residential area occurred prior to this screenshot but I was still in profit at the time of this save.
As you can see in the before shot, I'm in profit. I then proceeded to address my huge industrial demand by creating a downtown area mainly comprised of office space, with a little bit of high rise residential and a smattering of commercial around the fringes. The balance sheet in the after pic tells its own story. The biggest loss I'm making is on my metro, but I only made two changes to it between pictures, one was the addition of an underground plaza as the centrepiece of the downtown area, and the creation of two new lines. All lines are operating a single, High Capacity train.
As you can see with the 'After' shot, there has been a minor drop in income but a massive increase in expenditure. To be clear, I do not have the free public transport policy active anywhere in the city. The other change was that this new downtown area was built exclusively with trams and monorail in mind and all roads operate tram lines now. As with the metro, all tram and monorail routes operate a single vehicle. With the tram I have one going clockwise around the city, the other anti-clockwise, so two new trams. To offset this I upgraded some existing tram routes to a larger capacity tram and reduced the number of vehicles in operation. I also meticulously went through my bus routes, deleting lines no longer needed, and removing stops with little to no demand for them. I try to keep everything streamlined when I can.
Here was what my Public transport looked like before the changes:
And after:
Honestly I'd love to just throw up comparative saves for you but this city has been built with so many workshop assets it would never load for you (I detest the vanilla skyscraper assets) but I'm providing screenshots as best I can. I need to get to the bottom of this, because I can't see where I'm loosing 75K just through the addition of a new area., and a redesign of a low density area into a high density for aesthetic reasons, despite the redesigned area having 4.5x the population.
Moving on to the industry, I'll post screenshots when it happens, however, I've much reduced my commercial for now to prevent it from happening, but all it is is simply the icon above most generic factories such as you can see in the screenshots saying insufficient materials, factories that are right next to a cargo terminal, as in the
PT Before screenshot. It might help if I got an answer finally to my thrice asked question as to why my Cargo Hub isn't receiving ships? Neither do my cargo ports, and no it's not because I haven't lined them up properly, I have. The train works, freight ships just don't spawn.
Thanks for the ongoing help and advice and let me know if you need screenshots of anything else.
There is a switch over with higher populations.
The switch is making goods for employing people and exporting for money
To a more service base economy which will services your people but demands the goods you sell
But if your commercial zones are not fully developed or high land value then the return is not quite as high or easy as the investment you had to put into indy early game
Your income should be coming from your commerse or indy, your res cost you double what they give you in taxes
There is also a delay between more resources needed and more money made, and more money made will happen when commerce levels
Try placing a 15x15 park, with at least 7-8 atttractions, putting paths through sides and corners, then zone a shed ton of dark blue 4x4 upto the road. Pull the park boundry right upto the road. So some building wont quite be 4x4 due to paths. Now make park free. Now go kill a bit of that under leveled blue. Now watch that area go mental with level ups.
Not being able to make money with indy dlc, sorry dude - skill issue
I am aware, but a decade of in-game time has passed since the changes were made. Land value in the area is amongst the highest, it has all available services but the park I'm building is incomplete and so hasn't been districted yet. My industry is spread across four areas, three of which have a cargo terminal next to them, and all but one being very close to a residential area. The one that isn't is the largest and is in my main services area for the entire city. In total my genetic industry comprises of over 100 factories, I also have oil, ore, forestry, and farming with a Lemonade Factory and a furniture factory and a toy factory. I have got this to the point of consistent, uninterrupted output.
The new downtown area was originally built with more residential and commercial, dropping the commercial demand from its current 3/4 filled bar to 1/2 filled. I had so many problems with factories unable to meet the supply of goods that I redesigned it to be primarily office space which has brought the factories back under control. I'm aware of the weird way in which Colossal decided to calculate Commercial demand and I use the rebalancing mod to address that. Before I did the demand bar was maxed out.
