This is the second soft lock for a new DLC character I've had. Unfortunately the one for Malus was so long ago that I don't know if I have the relevant files any more. That on was on Vortex as well.
Anyways the soft-lock for Eltharion occurred at Turn 20. At Turn 19 all is fine and I can play the game without issue. Computer's turn goes by fine with nothing of note. Once I cycle to turn twenty I get soft locked. I can't click on any buildings or armies without crashing.
I noticed that a pop-up box appeared in my tech tree. https://steamcommunity.com/sharedfiles/filedetails/?id=2154283320
It seems like a help index of some sort? It's the only difference between Turn 19 and 20 I could find, so it makes me think it could be a part of the reason for this crash. It's textures are missing until I click on it.
I use a lot of mods, so I hope that CA doesn't have too much trouble because of that.
(I use a research speed mod which is why I have so many techs unlocked at turn 20.)
I have attached a Zip File containing minidump, campaign save, logs, etc.
