porblem with foundry map boss fight

was in Foundry t16 variant (via Kirac' mission) was clearing without problem until boss fight - i'm glassy, so after first death it got IMPOSSIBLE to continue fight becuase in the same millisecond you enter arena - you are instantly dead because of rats pack right on you at arena enter or some other thing, but you cant even blink out of it - every time you try to enter arena = dead. so just maybe remove rats and mobs out of this arena when player die so it could be reentered.
