thx, I'll check it, but I can't promise to solve it. Every patch, PAE gets more stable. I am sorry, it's a long, long road to find out, that some XML settings doesn't fit and cause problems, things that are unspoken, eg: setting a land unit into a pirate (it's just XML: HiddenNationality=1) causes CtDs. PAE has lots of new features. Only time can say, if they all fit in all eras, with all nations, in multiplayer and so on....
so please, be patient, Patch 3 for PAE V will be again more stable than any previous version before.
