I changed how jumps operate as I believe they are the source of your clipping issue. I believe it is something about being caught by an ANGEL at the exact moment you landed from jumping over a fence, respawning before the jump had "completed".
I went over a great many jumps in an attempt to remedy this issue.
Interesting that the RABBITS are sometimes dead, couldn't presently say why. Chippies might be pathfinding like TOOLCUBE to a degree, bumping against (invisible) events. I blame their animal senses making them nervous, which I suppose they well should be.
