I encountered a bunch of physics problems while building a lander that incorporates a service bay. Whenever I step on or into the bay, my kerbal loses its footing and starts ragolling or freezes momentarily and tips over. I tried moving the ladders around, removing stuff from the top of the bay, removing experiments from the bay and rotating the bay itself, but nothing helped. I also tried hacking gravity, RCSing on top of the bay and then unhacking gravity... still the same problem. Strangely enough, on one of my older attempts everything went fine.
