No idea about Totalise (I haven't played any of the non-vehicle-navmeshed Normandy maps much) but I'm almost certain now that the cause of the Goodwood CTD (with the AI mod) is the British PIAT anti-tank weapon. With the standard AI mod files, Goodwood CTDs virtually every time, even with the static Pak40s replaced - with the PIAT files removed from aitweakweapons.zip, the map CTDs maybe 20-30% of the time.
I don't yet know what it is about the PIAT that's causing the crash. It's nothing directly to do with my mod - the reason removing the modded PIAT files prevents the CTD, is that the default FH2.25 AI data for this weapon makes it almost impossible for bots to fire it (minimum range 290, max range 300, IIRC!). It's almost certainly an AI/bot-related issue, as I've never had a CTD when firing the PIAT myself (I deliberately tried blowing up as many things as possible with it, including static guns, unmanned vehicles, and friendly vehicles, in an attempt to find the cause of the problem - no CTDs at all). It doesn't always crash the game, either - I've seen bot kill messages for the PIAT.
The Panzerfaust definitely doesn't cause any CTD issues, but I'm not certain about the other AT rocket weapons. I'm going to try running Luttich with the bazooka and/or Panzerschreck disabled to see if this fixes the CTD on this map.
As a temporary fix for Goodwood, I'll upload a new aitweakweapons.zip with AI usage disabled for the PIAT. I'm also working on a modified Goodwood which, as well as the static AT guns replaced with mobile ones, has the British M5A1 halftracks (these work OK with the AI mod), different Panther colour schemes, and slightly tweaked AI strategy files.
