Vaal Foundry Map needs to be updated

Please add a way to leave the boss arena on this tile set. This needs to happen, there is no way to go back and continue looting or kill any mobs that you may have missed. You can end up soft locking the map into a fail if you accidentally miss a rare monster since boss kills doesn't autocomplete a map. Additionally you can't rely on only having 1 monster left on the map either as a way to say its safe to enter the boss arena, since you can have packs spawn in the boss arena that you would be unable to see until during/after the fight.

For the campaign area it wasn't a problem since you could go to town / waypoint back into the upper area but in maps you just soft lock the map by accident. Please fix this ASAP

Also can't complete due to an essence dropping in the middle of the boss arena. Very frustrating.
