Collision problems (explained and shown in video)

Here’s the video:

should be an easy fix, hit the box that represent your floor(at 17 seconds), you got it at static, but you give it a triangle collision bounds. uncheck the collision box, static objects do not need it. a good example for why it doesnt need it is due to make a hole in the mesh you will see triangle bounds will screw things up, while a static object without bounds will act as it supposed to.
