Spent an hour getting to wave 50 on Legend Midtown, upon getting to the boss room we all rallied the flag then were unable to activate all the switches, top and bottom switch activated fine but no matter what we done the middle switch would not activate. we were getting hit markers on the switch but nothing would happen. We tried multiple times to find a solution, two of us killed ourselves to see if that worked, then 2 of us left and re-joined to see if that would help all to no avail. Ended up just having to sack it off at the final boss door because of this bug. Received no error codes or connection issues throughout the entire run.
