Just played a skirmish with Kraken, Hyde, Bucket, Val, and Maggie on Orbital Drill. Kraken and Maggie were both passing through a wall on the tunnel/landing pad to the west of the orbital drill. Once inside, they were stuck and couldn’t get out. Very irritating as a level 3 Kraken.
Both were going through the wall on the sides of the structures that look like vent ducts, on either side of the stairs.
