Terracotta Soldiers Fail to Animate

In the Channel map in the large room with the sarcophagus and an army of Terracotta Soldiers, there was an Abyss. Some soldiers started walking towards the Abyss after I killed a few Abyss monsters. These marching soldiers were not targetable. When I activated the sarcophagus and killed everything in the room, I noticed that some soldiers did not animate, and count among the monsters remaining. These were almost certainly from the group that animated before I started the event.



Edit: Happened again on another Channel map.
