Mortal Empire - Chaos Invasion issue
Hello, thank you for your hard work in making this mod. I have been enjoying it quite a lot so far.

I have been having a problem with my campaigns. I am playing as Archaon and, when the Chaos Invasion spawns at turn 150, Archaon is wounded for a very high number of turns (multiple thousands) and I am given the option to replace him (though not given lords to choose, leading to his army disappearing). I also gain control of various heroes that spawn around the map and maybe an army in the Chaos wastes.
I have also had a problem where a hero reported in the action list is different from the one that performed the action. (For example, a high elf hero was shown instead of an empire hero.)
I assume this isn't how the chaos invasion is supposed to play out in your mod, and I'm looking to narrow down possible causes for this.

I play with no other mods that modify the chaos faction, though I do use Crynose's Faction Unlocker but I have the compatibility mod alongside it for Ultimate Chaos.

Other mods I use that modify factions are:
Cataph's Kraka Drak
Cataph's Southern Realms
Expanded Roster - Orcs
Expanded Roster - Goblins
Expanded Roster - Beastmen
Expanded Roster - Kislev
Whysofurious' Additional Lords and Heroes.

Other mods I have are GCCM, Community Bug Fix, Runic Forge as well as various cosmetic mods.

From the mods that modify factions, none of them change the chaos invasion from what I understand, being limited to adding units to their respective factions. I though initially that Whysofurious' mod might be the cause but I played through and campaign and Archaon still ended up being wounded.

I know it can be a bit difficult to know exactly what is causing the problems, but any ideas?
