In the Burrower Emergency quest at Camp Hathor, the second map that is infested with burrowers is a cave divided in two. There is the non-optional section of the cave that one has to go through in order to go upstairs, and there is also an optional section with a dead prospector. Both sections are infested with burrowers, but the burrowers could not transition from one section to the other in previous versions.
In 1.0.4.17, they can. While I was fighting the burrowers in the non-optional section, the burrowers of the optional section migrated and joined in the fight.
I did not see how the migration happened. I just noticed that I was fighting many more burrowers than I expected in the non-optional section, and then I went to the dead prospector room and it was empty of burrowers.
Steps to reproduce:
- Start Burrower Emergency quest.
- Go through first burrower-infested map and enter the cave.
- Start fighting with the burrowers.
- The burrowers of the dead prospector room migrate and join in the fight.
