Monster Stuck between Objective and surrounding objects, and cannot move


I was Goliath Stage 3 at Weather Control Objective, Trapper put up Dome, and I sort of got caught in the ground behind the objective. The tree next to the objective (which looked knock-down-able), would not budge, I could only move a few meters around me (my feet looked like they may have clipped through the ground?).

I finally jumped to get out of the tight space and I ended up falling in front of the objective… but was again stuck. This time in mid-air between the objective and the surrounding structures. I could not fight back, my foes picked away at me as I floated, endlessly and helplessly.
