Certain monsters on the lift from the mount of Magnatz to the Lowerdark such as bats/dire bats cause the lizardfolk to go hostile when they are engaged. This resulted in a player being slaughtered brutally by him. This should be fixed rather urgently as it can trap you upon the lift.
Character that was killed and respawned as a result of this bug's name is Jaqicho Woodwright who the lizardfolk turned to attack after he engaged the bats.
This has happened a while ago with bats & dire bat but he wiped out 3 of us, so it seems this is a potentially recurring issue...
