Gotcha!
Well, for Gedemon, I've attached my savegame to this post. I only have this mod (YAHEM) installed.
So far it has crashed the first time I start a game, while it's loading, in the middle of the narrator speaking, trying to access the civilopedia and between turns.
thank you

played 30 turns without crash so far. and no problem with the civilopedia either.
can you play on vanilla huge maps without problems (continent or terra for example ?)
