Rigid object behaving differently in Object and Edit mode? Ok, so I'm a total noob at this. However, It seems weird that an object, in this case a modified cube shape, behaves differently when dropped from a hight depending on if it is viewed in object or edit mode. Im using the 2.8 Beta. In Edit mode, my object drops and hits a passive floor plane, bounces a bit and comes to rest. All good. When I switch to object mode however, the object drops and hits the floor normally, but after that it won't fall over! It just stands there on an awkward angle and moves a little in super slo-mo!? 

Any ideas?
I have just solved the problem! 

I exported the object from my Blender file as an .obj file and imported it back. Now it behaves perfectly with physics and other stuff!
