Thank you all for caring.

I use vanilla with three modded files (modded by myself). I changed the bulding-times for units and maxed most units from 160 to 240. Also I did some minor changes to the buildings, so every Corebuilding produces a law-bonus to prevent unlimited barbarian-invasions and a little health for the people. Minor ports produces no ships and assassins can't be build. Then very, very little in the campaigns strat-file (impossible factions went to unlocked factions, I got some more gold (Damn, I'm caught ;) ). That's all.

The game starts as normal, the campaign, too. After ten hours Thrace moves several armies to a certain city, one army is repelled by the Scythians and the crash takes place (perhaps because of the next unit in order or because of this repelling event). But I did notice that Thrace had no characters. I observed the whole thing with toggle_fow and I think I am able to see then all characters (but not the other units, very funny ;) ), but for Thrace there were no ones.

changed files:
- buildings: is working fine for me, wrong spelling would result in a immediate CDT after my experiences. And furthermore I think I own all buildings I changed there.
- units: The same is here but furthermore I replaced the file with the original file. Same result.
- Campaign-strat: Hmmm... well... only things the game would complain at startup I think ....

I use 1.2 of course. I played the game several times, so my pc is not the reason, I think.

BTW: The kill_faction cheat is not working, as almost every cheat there. Some works, most not. Perhaps I am too dumb for such stuff.
