Need help with Leclerc bug report

Leclerc exhaust pipe does not collide with terrain
Leclerc exhaust pipe can detonate HE/HEAT but only once
Leclerc exhaust smoke does not collide with exhaust pipe.

For some reason I always get a error on the bug report site so if someone can please assist that will be great and appreciated.
