When nothing else spawns it usually means
- You didn't kill an enemy.
- You started to have desync / disconnection.
The latter is quite common close to patch release. This can happen to the entire instance as well, so if someone starts disconnecting and other players progress, more enemies might not spawn. When the player inevitably disconnects finally, the server decides to spawn the new enemies in as it should have.
#1 I already stated I killed everything and nothing else spawned
#2 I was connected the whole time until the timer ran out.
Read before responding. Let alone it’s a 1man quest so others have nothing to do with it.
