What's wrong with Alexandreia-Ariane?

[Taedius]

I've bypassed the problem for now, by retreating when the battle came up. But I'll have to take that town sooner or later. We'll see.

As for XSamatans points: Haven't tried autowin. The pre-battle crash seems to have been a one-time thing.
Zero movement points, don't think so, but not sure. They were stuck in the towns zone of control, first turn of siege.
No move_character.
Plain 1.2 + fixes, in effect. I tried earlier to install a modpack, unsuccessfully. Could be something there, I guess.

Create a backup of your save and try it once with auto_win, normally this does the trick.

Thanks, if this keeps up, I'll try that.
