Hi,
Groups of monsters are frequently bugging out now in Heavy Duty, specifically in terms of pathing through an open gate/door. This is noticable right after starting a game: groups of rathounds will sometimes cluster around an open gate instead of going through (e.g., reclaiming the outposts outside of SGS). It's like a traffic jam.
Also happens 2 zones to the north of SGS, there are 4 dogs behind a gate. If you close the gate to let them group up, then open the gate again, they are jammed and can't get through. I believe the frequency of this bug has increased considerably from what it once was. This could simply be bad luck, however.
Thanks to Styg and the rest of the team, and the fanatical beta testers, for their hard work! I am enjoying it so far.
