So I’m in a random game and I used my binoculars and the reaper is at 3% health and it won’t move or attack or do anything but it’s shields are up so we can’t attack it
To fix that (hopefully), host needs to restart his/hers game.
But for immediate thing to try: collect bunch of red gas tanks, place them all around the Reaper and blow them up. This should give Reaper some air time and set it on different spot on the ground. <- This only helps if Reaper is frozen because some terrain collision issue.
Same can be achieved when one machine walks/runs into another one and pushes it aside but that takes a lot of finesse on player part.
