Picture says it all. Tested with the MC-172 as well. It makes sense that this would happen, but at the same time it really shouldn't. To reproduce it. build an MC-172 and place a slab under the front wheel, then remove the slab.

Huh. It should be considering wheels at Z=0 to be rear wheels. Though there might be some code oddities that are causing that issue. Rotations get nasty when you have 0s around. Will investigate.

Canceling as this is due to intended behavior with the collision boxes and not wheel placement.
