After getting teleported into the void and killing all enemies, my teammates have normally returned to the main map.
But I was stuck there with no way of going back.
I couldn’t kill my character (tried spamming rockets under my feet with Benedict), and the key to respawn in base doesn’t seem to work in this part. I could only see my teammates far away on the map, check the boss’s health bar, and dance around when taunting.
I imagine this could be a game-breaking bug if it happened in solo mode.
