On my 'true collision' system, I have primitives attached to my hands and feet so I can interact with both objects and avatars. As such, they are parenting to the respective joints.
The problem is upon going to another domain, sometimes the property "Collide with my avatar" gets ignored and causes a physics fiasco where you get pushed infinitely. Even though my script sets it to false, it seems to fail at times.
The only culprit I can think of is that sometimes the sessionID the entity is comparing to doesn't get updated, but that's the best I can think of. Due to another bug (will post and update soon), this means the user cannot even use the tablet system to resolve the issue.
