Discussion
The last release was closer to playable than I expected. We transitioned from people converting games to see what it'll be like in the future to people converting games to actually try to play. This exposed lots of quality problems. We've resolved a great many of those, and will be working to keep quality up in the future. Of course, any feedback will help us resolve bugs.

The major features for this release are diplomacy-related. Vassals, PUs, initial agreements. But not wars, yet. Wars are complex, and will need their own update in the future.

We haven't been able to test against any 1.09 saves, so for now I'm saying we don't support them. The next update will be specifically for getting the converter to work with 1.09.

I've also released a new version of the converter mod that has all religions and cultures (including up to 1.09, because there were no additions or changes there).

What's Not Converted
Armies
Wars
Buildings
Sliders
Trade

If I understand this correctly, we might be able to do a bugfix branch and a new feature branch in Mevurial pretty easily, which would allow us to better get bugfixes out the door.

I guess just update to revision 305 (or the relevant new revision with the branches), do your change, check it in. Then don't merge things?

 

[Thobewill]

Awesome! Works like a charm.

Hi! first time posting, been following this thread excitedly. I get a save file created, from my game playing as the kingdom of jerusalem, but it crashes EU3 either after a set period of time, or when I attempt to save the game (or autosave). this is using the latest update of the game, 1.09

Save file mentioned: View attachment historicalconvertjerusalem1401.zip

keep up the good work folks, and let me know if there's anything else you need from me.

Oh, also the log file shows that it tries to open the converter mod file for religions, even though I don't have the converter mod installed at all.

Well, I'm seeing the same results, though nothing is jumping out at me for a cause. Maybe one of our analysts can figure it out.

In the meanwhile, can you upload your CK2 save for me to run a test conversion with?

 

[Sobotnik]

Hi I've been following your work and I have to say I think you are all doing a great job on it.

However, I recently got the republic expansion, and I was wondering how Republics would be handled in the conversion?

 

[Carthade]

So, um, I replaced the old converter files with the new files, and now instead of running the command prompt, it shows maybe one or two lines really fast and then exits.

edit: nevermind. Forgot it replaces the config file too :blush:

 

[Jeremo]

I'd love to upload my save, but apparently it's a beast even zipped. preferences for getting it to you?

That actually needs some discussion. Analyst types, you around?

I think they should get the merchant republic government, plus a CoT at the capital. Provinces with trade posts would be added to their trade league. Not sure to do with the family holdings, nor what to make of the trade post upgrades, to be honest.

If I had a dollar for every time I've done that (or something similar)…

Most people use various download sites (I don't ever remember their names). Better, it should probably fit into one of the free dropbox accounts. Let's try that.

 

[Idhrendur]

Right, I've created a 'Major' branch, and a 'minor' branch, and will create a 'bugfixes' branch as soon as I have something to check-in there.

For clarity's sake, major features are ones that support what the first post says will be in the next (major)release.
Minor features are anything else we're adding.
Bugfixes I hope are obvious.

An upgraded merchant post/s in the same province as the CoT could give the owner merchants in that CoT at the game start possibly.

how's this work then? https://docs.google.com/file/d/0B21rnwUQb0WpMWg5QUgyVC1xVzg/edit

I think they should get the merchant republic government, plus a CoT at the capital. Provinces with trade posts would be added to their trade league. Not sure to do with the family holdings, nor what to make of the trade post upgrades, to be honest.

Could upgrades to the trade post just be factored into whatever is used to determine buildings at start? For example, if there is a top-level garrison, and then all of the holdings have the best available wall, perhaps give a fort level 2? Or just something like that; I know most holdings are fully upgraded by the end, so maybe not the best answer.

Alternatively, a fully upgraded trade post could increase the amount of whatever trade good is produced in that province. This might overpower coastal provinces a bit, but would give a slight advantage to a stronger trade empire, without completely throwing off balance.

So I tried the new version on the save I had uploaded here - the good news is that I had correct unit types, Latin, rather than Muslim (though it had still set me to Muslim tech group).

The bad news is that a few seconds after combining three units into one group and adding a general the game crashed. Does EU3 produce a log file anywhere?

 

[Tureis]

How will HRE convert if it became a Republic?

 

[dtremenak]

The bad news is that a few seconds after combining three units into one group and adding a general the game crashed. Does EU3 produce a log file anywhere?

The EU3 logs are usually not that useful, but I can tell you that what you describe is almost certainly an ID out of range or in conflict. Which doesn't surprise me too much...I think we're still outputting temp IDs in the file headers.

 

[Byzan]

..Where exactly are the CKII save games so I could test this out?

 

[Idhrendur]

An upgraded merchant post/s in the same province as the CoT could give the owner merchants in that CoT at the game start possibly.

Interesting. It'd be lots of details to work out, but assuming it's not to tough, that's a good idea. Still seems a little weak to me, but it's a good start.
