Excellis Aurafix is extremely desync'd on Maven 10-boss Invite (Gauntlet)

1. witness Excellis Aurafix (boss of residence map)
2. do a 10-boss
3. trying to kill this monster leads to him running around wildly visually but is actually standing still/not where he appears to be until he 'rubberbands' back and goes to his actual position for a time before doing it again.

This is/was in gauntlet.
