Just that vehicle of the AAI list, the others work correctly.
Installing both this mod and AAI Vehicles: Flame Tumbler gives an error message from Bob's Warfare, but as that vehicle is the odd man out of their list the error is most likely theirs.
Still, you might make a mention listing incompatibility.
I'd inform AAI as well, but comments on that mod are disabled.

the actual error message is essential for knowing what the problem is, however, since you mention "Flame"... Make sure that the setting "Vehicle flamethrower starts fires" is turned off. That one is turned off by default, and is known to cause issues with other mods.

That setting is indeed on for me, so that is probably the reason for the incompatibility.
Good to know, my preference is for that setting in stead of the addition of the mod I mentioned.
I later found out their other mod for a flame tank had this problem as well. All their other vehicles do work for me.

Thanks for the reaction, for me no other help is needed :)
