I'm using Windows 7 and DMUC 4.45 with Additional Units Mod 2.8 and getting CTD most of the times i finish siege battle, both defense and attack. No matter did i lose or win it still crashes on campaign map loading screen at ~75% loaded. I tried disabling different submods and option in ETW, changed the language and checked game cash, but it doesn't help. I started to experience such problems from first installation of DM, it was version 4.2 . I looked for same problem reports through some forums and read that it may be caused by general getting some ancillary after battle. I can play sieges without any general but it'd be retarded without any morale bonuses from experienced general.
Also i can say that all other battles are ok and i can finish them with 100% chance.
After each crash game makes a crash dump file ~120kb, but i can't check it with any programs i know, i can upload it if needed.
