Battle Royale Reloaded

That sucks, thanks for having a look at least.

No I won't since other mods that have a WST tag will break
I might be able to exclude countries that you can't justify on, but given that Battle Royale's logic on choosing a country for a naval war is convoluted and completely not human-readable (no idea how or why did the creator do that, although I think HoI4 modding support had way less capability back tthen), it sounds like I'll need to rewrite the whole thing from scratch
Although now that I've rethought some priorities in my life and don't overdose on hoi4 modding anymore, me actually rewriting the rest of the remaining original mod is a possibility

I don't think it'll tell you much, but here. [pastebin.com]
I know nothing about how any of this works, but I imagine you might need to code in the WST tag as an exception to the war declaration event.

I mean, upload it to pastebin or something like this, please don't send the whole file in the comments XD

Please send the contents of the file C:\Users\[insert your username here]\Documents\Paradox Interactive\Hearts of Iron IV\logs\error.log while this happens

Doesn't seem to be compatible with Every State Independent on the latest patch, it'll repeatedly start a war on the blank neutral country, force a white peace and then start the war again.

No problem, most don't even say sorry
But I do recommend testing a faulty mod without anything else enabled next time

Yes sorry I was mistaken, I just narrowed it down to an issue with Rt56

I also checked it with the new version and it doesn't crash

100% not the mod's fault, it doesn't even do anything with the game rules
