Come at me behemoth.
This happened on five different occasions. With it happening to our trapper, me and a party member reconnected to another server and oddly it happened to me as well but instead of falling through the map I got stuck in the sky and was for the most part free to move wherever an invisible wall allowed me. I tried going Idle as this has been known to fix some bugs but it didnt work, instead it made me fall through the map and unable to heal my teammates and also not able to die.
Some pictures of the weird indecency.
