So if you move static objects, it messes up their collision mesh somehow in a way that makes collision unreliable from that point on. Might be the objects going to sleep after some time... Maybe the static objects themselves go to sleep and aren't getting woken up or something, even on collision with other objects? It seems like the issue goes away if the static object moves fast enough.\r\n\r\nIf that's the case, it might be worth it to check to see if a game object is changed in position, rotation, or scale and to wake its physics body up (in the scene itself, since this could happen even on a \"non-active\", un-programmed game object).\r\n\r\nAnyway, here's a test blend file. You can see the right-most \"Sacky\" object completely and totally fall through the static moving object, and the second \"Sacky\" and red cube (rigid body) completely stall in the air a few seconds in.\r\n\r\nhttps://app.box.com/s/z84103m6vwmz9rq4zo3y1fv0xs4e5i5i"}}
