Ever since the update, I've had many cases when my plane is going about its day until it GETS CRUSHED BY THE ETHER into the ground, which is as startling as you can imagine. This happens especially with flat bottom wings, which are typically the most likely piece to freak out anyway.
@jamesPLANESii Oh no. That's against my religion. XD
Have you got any negitive mass blocks on your plane?
They do that for some reason... I still don't know why though
