Steaming Springs - Boss bugged out. Disappeared.

For some reason the boss bugged out for me on a Steaming Springs map (lvl 78).

Running Gas / Oil / Explosive Grenade combo with Explosive Shot & Ripwire.

Got the boss down to probably 40-ish % where she throws out the bone circle to trap you in. I rolled out of it and the boss dove down and never reappeared.

The boss fight is still in progress with the boss music playing, but when I re-enter the arena there's no boss. Tried exiting to character screen multiple times. Could not get the boss to come back up to finish the fight. Unfortunately appears to be a bricked boss fight on this one.

I got another bug just now on this map/boss

Killer the snakeboss but the map wont let me out of her arena.

Som im stuck in here but i havent finished the map.

Just happened to me, too.

just happen to me the same
