Seems like Tower of Khrakk / Battle at the Golden Monument
Crashes when loading from campaign map when playing fresh Kholek campaign
I have the GCCM assets subscribed, as well as main GCCM.
Also have some other mods included, but mostly UI/scripting stuff

It also crashes if starting a Custom battle there as well.

I posted this to the Map Makers discord under #bug_reports
