So, I got the killing blow on the boss just as he did the vomit attack and I seem to be permanently slippery now, and, as such, cannot use the valve to leave the arena.

I haven't submitted to support yet because I don't have my player id written down, so I'd have to quit to the title, but intend to submit it whether or not I manage to get help here in getting unstuck.

I've tried changing equipment, changing weapons, using, dropping, and throwing items, and playing around in the options/menus.

I can't move faster than a walk, attack/aim including rage attack, use items on the ground or intractable objects, or pick up items.

I can defend, throw items, eat items already in my inventory, walk, jump, and defend. Out of inventory items though(had two, tested eating and throwing).

Any ideas before I have to scrap him and grind up the money to salvage? :/

Edit: sneaking also didn't work. Scrapped it, salvaged him with the coins from tdm rank, and submitted the situation to support so they can patch it in the future hopefully.
