DTS Collision Issue, What Could Cause This?

Hello everyone. Recently one of our artists sent me an animated flag to use for one of our gameplay modes. The flag works fine in TGE and in TSE likewise it works fine at first. However if we approach it and the flags collision box touches the players collision box it crashes TSE. We modified the collision box to put it at the top of the flag for testing and tiny, and then there is no more crashing. But the gameplay type we are using is a form of advance the flag, so we need the collision box to be on the pole instead.

Any ideas what could be causing this? I did a trace but there as really no information in it that would even lead you to believe there was a problem. It just crashes immediately.
