Ghost CAN lie due to multiple reason


- Bad multiplayer server sync. The ghost doesn't register your move correctly.
- Pressing E at frame 500/500 (or x/x) in SP. Tori and uke will fall.
- Force being applied to some part of your body. It makes them spinning. It's a bug in the phys engine. Usually happens with a DM'd part.
- Extremely rare case of ghost truly lying. Only happens with some collision. (http://forum.toribash.com/showthread.php?t=273710)
- Wrong TB/TBserver version (http://forums.toribash.com/showthread.php?p=4361012)
