Thanks for the feedback + bug reports!
Jeep CTD - I've now fixed this, it was caused by a couple of errors in the vehicle's objects.ai file (which caused a CTD when a bot attempted to switch position, or was displaced by a human player) After fixing it, I haven't had a CTD on Cobra so far. I'm wondering if this could be the other cause of the Luttich CTD, since this map also has a Jeep or two; I suspect it may also be the cause of the occasional CTDs on North Africa maps which have the non-SAS British jeep (which shares the same AI file as the one on the Normandy maps)
I'll put the fixed Jeep file up for download soon - as most of the Normandy maps have this vehicle in, it's a fairly critical fix!
I haven't looked at the train yet, but I assume it's just due to this vehicle not having an AI file assigned to it. Though I once got a CTD on Totalise when attempting to use the train myself, no bots were nearby. It definitely works OK in multiplayer.
"USMC" message - This is weird, no idea what could be causing this. I don't think I've changed any files relating to in-game messages or text.
Tank MGs firing through things - Even weirder, this shouldn't be happening (and I don't think I've ever seen this myself). AT gun shields don't usually provide 100% protection from small arms/MG fire, due to their shape and the open vision ports - but MG fire certainly shouldn't go straight through them, or through scenery.
Bots using AT charges - They're definitely able to use these correctly (some of the time, at least), I've seen many kill messages for these weapons (not all teamkills!) and have been killed by Geballte Ladungs a couple of times myself.
Limiting bot AT kits - Unfortunately I don't think there's any way this can be modded - bot kit selection seems to be hard-coded. It's particularly annoying on the North Africa/Greece maps, as bots are unable to use AT rifles effectively.
BTW, the limited range isn't to prevent crashes (the PIAT CTD isn't related to the weapon's range), I just set the range to (approximately) the historic effective range of these weapons. In the default FH2.25 files, AT weapons have very long ranges - on some maps, like Luttich, they can fire at you from beyond visual range - but, as the minimum ranges are so high, bots rarely get a chance to fire them, so the issue is less noticeable. With earlier versions of my AI minimod, I fixed the minimum range without reducing the maximum range enough, so you had bots firing bazookas/schrecks at you from miles away.
Crash on El Alamein - Never got a CTD on this map myself, this was one of the maps I tested shortly before releasing the new version. However, I'll try it again.
Mortars not firing at infantry - Still not sure why this is, infantry are their main target priority in the AI file, followed by guns and unarmoured vehicles, light armour, and tanks.
And for those of you looking to play on new maps here ya go...
Excellent work!
It might be worth posting this in a new thread so more people will notice it, also feedback + bug reports can be posted in a specific thread this way.
After fixing the Jeep bug, I played a complete game (as the Allies) on Operation Cobra with no CTD. The AI on this map appears to work very well - although I can't comment on the pathfinding around Hebecrevon village as the fighting never got this far... this map is definitely very challenging for the Allies with loads of emplaced AT and Flak guns, which the bots use all too well (the 88 between the German main base and the farmhouse got me at least 3 times when driving a tank, and then shot me down twice when I tried to use P-51s to take it out
).
I did encounter the double-cap problem on the farmhouse CP, though. Also saw both friendly + enemy bots and tanks hanging around friendly CPs when they ought to be attacking, I'm going to try adding a strategies.ai file to this map to see if this will make the AI more aggressive. The Allies should be constantly on the offensive on this map, whilst the Germans should probably be on the defensive at first and switch over to a counterattack when they lose a few CPs (but should still give defensive gun positions a high priority)
I haven't tried the other two maps yet (will try Totalize next to see if the Jeep fix has removed the CTD) but noticed a problem with the folder arrangement for the Mount Olympus files - the "32" and "64" folders are all in the SP1 folder, 32 should be in SP2 and 64 in SP3. This is presumably why the 32 and 64 player versions of this map can't be started from the main menu.
