um...so I figured out what was the problem. Seems like in the world management screen there are TWO san myshunos. (No idea how-) The bugged one was always at the top while the normal one at the bottom. Thank you for the reply though! If it weren't for me trying this out I never would've noticed. I think this bug is another bug in itself but it doesn't affect gameplay so I'm fine with it. Thanks!
2 San Myshunos??? That shouldn't happen, you should only have one. It could be a serious issue, if not now, then later on if you continue to play the save.
If you start a new save without anything in the mods folder but the resource.cfg file, do you have 2 San Myshunos then? If you do and since you already did a full reinstall, it shouldn't be happening. If it is, then there has to be something in your mods folder that is not playing well with the game. I have no idea what could be causing this really, but a mod is the most likely reason.
Hope this helps
@lumi3437 Did you ever remove a world-creation mod? That can cause this issue. There's a bug report here for when it's not that (test in a new save): https://answers.ea.com/t5/Bug-Reports/WORKAROUND-Maps-from-DLC-appearing-twice-on-Overview-page/td-p/11565374
