the log file has a metric crapton of lines that read: "Error: bad relationship modifier in ruled_years"
1.09 is not yet supported.
plus another bunch of warnings about how some titles never had a holder
Believed to be harmless. We leave them in the log so that if those nations convert AND cause problems, we can identify possible causes.
and another bunch about not being able to assign a government.
Normal, unfortunately. As idhrendur wrote just a little ways above, government and tech groups both have some problems.
Plus, I got the line, "Error: Could not open H:\Steam\steamapps\common\Europa Universalis III - Complete/mod/Converter/common/religion.txt" which is odd, since in the config file, I have "EU3directory = "H:\Steam\steamapps\common\Europa Universalis III - Complete""
This just means you aren't targeting the converter mod, which is fine (we support both ways), but you'll get some strange tag assignments.
Edit: I've just fired up EU3, and the select country screen for the converted save is... interesting. It's assigned names in some very strange ways, and places nations (so to speak) in some strange places.
See the first post in this thread. If you don't use the converter mod, you'll get strange tag assignments.
Edit 2: There are also no trade depots showing up. In fact, EU3 immediately does a CTD if I so much as mouseover the button which creates a CoT.
Known problem. Let the game run for a month and a day (or is it two months?) before trying to manually create COTs. EU3 will create one automatically, then assign every province to it, and at that point it should all work OK.
I should have mentioned in the first post that I also has the Islamic tech group (at least, I was being prompted to upgrade to Muslim troop types),
As Idhrendur wrote above, tech groups are quirky at the moment and will need to be fixed.
as well as no money
unsure
You should have 13 months' projected income.
no troops (well, I didn't have any levies mobilised at the end of my CK2 game, so that probably explains it)
This is normal...levies never convert, and retinue conversion isn't implemented yet. You also have no manpower, which is a known problem.
-40 prestige
blink
I believe this happens because EU3 deducts prestige for the cores that you lose on the first day. The core loss is a known problem that will be fixed sometime. Hopefully once that works OK prestige will be more...predictable.
and the National Decision to form the Irish Nation... which promptly changed me from the Empire of Britannia to the Something of Ireland.
Working as intended. If Ireland does not exist, you own all Irish provinces, and you have Irish primary culture, you may form Ireland, regardless of your current title.
