Pitty about the AA - Sorry I sounded like I was pointing an accusing finger, Drawde. You've already done so much for AI in FH2 since 2.25 - I was just going on the obvious conclusion
No, I haven't modified anything in my stock files. In fact, I had to reinstall FH2 recently and the only thing I added was the whizz from BF2 Vanilla. Bots fire and destroy light armor and I have seen them blow up a PzIV just today. They do miss often, but no more than zook or shrek at average firing distance and they have greatly increased range...
If the issue is with you alone as I haven't heard anything from CannonFodder, DJ Barney or Zoomotorpool, then its possibly just ill luck or you may have set AI difficulty lower than us... Try playing in COOP and set the AI difficulty to 80 or higher.
Before you made aircrafts fire their cannons again, I got the BF109 to fire bullets accurately enough to take out everyone in an APC and another time, to blow up a truck.. And that requires at least 3 - 4 good shots on target since trucks have wooden rear sections that don't take any damage... But this, only when I set AI difficulty to 100%...
Now I won't recommend testing on that level, but the default difficulty of 50% makes bots shamelessly inaccurate.
Perhaps for the Luttich issue we might all have to get involved. Let's post up some files to replace our stock Luttich objects file, each with a all vehicles removed but one (Each file with a different single vehicle ingame). With those with enough computer power, I will say set the bot count to something like 80 so we can speedup the simulation. Then play the level and see if it CTDs... We will clearly know what vehicle causes it in such a case.. But it will require all we SP enthusiasts. And fret not, Drawde - This one seems easier to spot than Goodwood's, which might be interraction with some corner of the map by a single bot and cannot be isolated in this fashion.
Here are some facts we do know about the Luttich CTD:
1/ According to some, it occurs when you go to the church base - I experienced this myself once and it seemed to much of a coincidence to be shrugged-off
2/ According to you (Drawde), it occurs when you are in a vehicle and got hit by a zook or faust.
3/ it occurs anything from 5 to 20 minutes ingame rather than during load or immediately the game starts, implying an action caused by either the player or a bot in the course of the battle.
Anyone want to prepare those replacement files for us to start this test?
