[BUG] Mercenary in party

Me and my friend have been searching for a specific mercenary now for 2 days and have spent thousands of chaos on this. Today I found the mercenary and we were in a party, he joined my map but was unable to interact with the mercenary.

If any developers or anything can see this, please can we get this merc given to him as it's been a supposed bug now for so long and information about these things are scarce.

Thanks
