Orthodox Papacy and weird nation adjectives.

And another interesting one I found, an uncolonized island is the emperor of the HRE

@Thrawn I don't know why this is happening. None of the orthodox cultures have predefined name so that shouldn't be an issue but I will look into solutions.

For the HRE problem; I can add events that will clear away any game generation bugs, but that will immediately triple the crash rate. I may create a more complex mod later on that has additional features at the expense of world generation stability.

I'm having a bug regarding custom nations. In some map generations (about 50%), when selecting a captial for a custom nation it will automatically give you all the provinces of another nation and prevent you from removing them. The area in which it gives you the provinces is always colonized and you are unable to select a captial in the vacinity of this area, due to the error message saying "This province is too close to another custom nation" desptite no other custom nations being created.

Thoughts?

I've run into similar problems with custom nations being spawned in map generations. I think it has something to do with insufficient numbers of tiles allocated for the random new world (which is how the random world is generated). I've added provinces and province names in the appropriate places but that doesn't seem to solve the problem. It's possible I missed something but it's also possible that I am completely off base here. Either way I am working on a solution but because these bugs to not appear in the error log for me it is extremely difficult to diagnose the problem.

I created a test copy of your mod to mess around with some things, like trying to create an HRE by event after world generation, or getting Protestantism and Reformed to work.

Unfortunately I can no longer get a Random World to generate, either with my altered mod copy or with your unaltered mod. Crashes at different parts of world generation each time.

Now, the error logs aren't ENTIRELY blank on this. The Exception error log times seems to match up with my world generation failures. But they are hardly helpful, and seem to be some sort of memory access violation, looking similar to this:

######## EXCEPTION: 0xC0000005 at address: 0x01269EE9: ACCESS VIOLATION write attempt to address 0x37C17B44
Version: Unknown Version
08/26/16 23:59:02

Might be completely unrelated, but it can't be a coincidence that there are eight entries in the list corresponding to my eight tries at World Generation that have failed, all at the correct time periods.

It's a bit over my head to troubleshoot this, but maybe this will help you?

I'm no expert and have next to no experience in these matters but what I believe is happening is the mod requires more memory to create the random world than just the random new world. My guess is that paradox put in a hardcoded limit of how much memory the game can utilize to prevent a bug in the game from gobbling up all available memory and crashing the whole computer.

Out of curiosity, how many gigs of RAM do you have? If I'm right then memory is the defining characteristic as to whether or not the game crashes. If this is the case, then it's highly unlikely I can do anything about it as this is hardcoded into the game. If I could I would be able to do so many cool things from increasing the map size to removing the province limit for individual tiles.

I have 8 GB of RAM.

I did have several web browsers, File Explorer and Notepads as well as EU4 when I was trying to mod the game, and normally I just have EU4 only, maybe this pushed something over the edge?

if this is the issue, maybe we could ask Paradox to raise the limit :). Or at least make it moddable.

Yeah I have 16 GB of RAM so that may be it if it crashes a lot more for you. I can try reaching out but I don't know where to do this or whether or not they'll even listen. The limit was probably put there for a reason.

Can't load my save game while not having changed the mods or settings at all.
