Issue title: Rathian may become trapped underground
Issue description: Rathian may burrow into the ground, if a part break occurs while she is in the air.
Status: Fixed in v64.
This happened to all of my pink rathians during the pink rathian event. I submitted a report and posted pictures and got no response. Kind of sad. Such a waste of an event for me. I was lucky that I had friends who I could party with and kill it for me.
