Sorry for my late reply. I checked each block of this tank one by one, and there were no MOD blocks that were not listed. There is a possibility that the "Weapon groups" MOD is causing the problem, so I uploaded one that does not use "Weapon groups mod". If it still doesn't work, please comment again.
