My Ant mount is stuck under the map in my world with my friends. We are already 12 hours into the playthrough and I am unable to hatch an additional mount because “i already have a mount following me” would really appreciate this change because I am unable to get my ant or the items it had in its inventory. Either a give up or a recall all option would be a life saver! 

My cousin and I have also had this problem. The work around we found was to build an Ant Nest, store the buggy that's "following" us, then withdraw it. It spawns at the nest and will return to it if it gets knocked out again in the future.
