Gaijin, why did you ruin the Croc?

So I like playing the Churchill Crocodile - but it turns out you can ammo rack it from the trailer in the back? The trailer didn’t do that before, what gives for it now? I don’t care if it is “muh realism” that a trailer holding all that flamethrower fuel could nuke my tank, it’s stupid and you know it and I don’t even think it could nuke a Churchill from the rear to begin with.
