Notes:
1. I encountered this issue on [Xbox series x]
2. I was playing [WITH A FRIEND]
3. I was playing as [BRUENOR]

WE'VE ENCOUNTERED A BOSS (DOUBLE BOSS, SOME "EAR-LOPPER" AND "BONESUCKER"). WE DIED IN THE FIRST TRY AND THIS IS WHERE THINGS WENT CRAZY. LOADING SCREEN WOULDN'T DISAPPEAR FOR A LONGER TIME, BUT WE HEARD AND FELT ALREADY THE VIBRATIONS OF MOB FIGHTING OUR CHARACTERS. WE HAD TO BACK OFF AND BLOCK CONSTANTLY UNTIL THE GAME FINALLY DECIDED TO HIDE THE LOADING SCREEN AND SHOW THE CHARACTERS AND MOBS. MY FRIEND WAS ALREADY DEAD AT THAT TIME, AND I BEARLY ALIVE. THIS HAPPENED SEVERAL TIMES BECAUSE WE COULDNT MAKE IT IN SUCH BAD HP STATE
