Fixed the crash related to the m4 mortar carrier by removing unnecessary code.
Lots of testing in the editor with units, btrs, light/medium/heavy tanks to ensure a better experience.
Further testing needed in game to ensure a more stable gameplay.

Finnish ISU-152: Temporarily removed from mod files to avoid DLC-related crashes. Unlimited ammo is gone for now, but the game won’t crash anymore. ISU-152 works fine, just with vanilla ammunition amounts.

M4A1 Mortar Carrier: Fixed the crash by cutting out some buggy code that was not needed. Works fine now.

T-60: Added dummy code to skip a weird missing animation thing. It never crashed for me, but just in case, this should stop it from happening. Might look a little janky when the driver gets out, but at least it won’t break the game.
