Objects Sink Into Eachother

Hey all, im having a few problems that i think are coming from the latest updates to ogrenewt - firstly the ogrenewt body attached to the character is sinking a certain distance into the ground now, and perhaps because of that, the player now gets stuck on the edges of triangles ( from tree collision on the environment ).

Before the latest updates this was not occuring - is there an issue there or is this something that i can fix?

updates to ogrenewt only, or Newton also?

Ah I found the issue wal, there was a conflict between 2 materialpairs... silly me
