Corrupted Ice Barrows Bugged, Can't Finnish

when i got to the second to last stage, where u have to spawn 3 minibosses in order to get the 3 blue tokens to advance to the boss stage, the third boss just doesnt spawn, i put in the 8 tokens and "Theorick?" spawns, hes a miniboss that can spawn anywhere, but doenst drop anything.
can someone help me or something idk, im sycuk here now.

 

First: Post your questions next time into the questions section of the forum.
Second: Well, the miniboss is a bit tricky. BEcause there should be two Theoricks, one with the name "Theorick?" and the other "Shadow of Theorick" (Something like this, idk). Problem is that the second one tends to remain in vanish most of the time, be sure u kill the right version.

 

Shade of Theorick does not spawn and hasnt been spawning for a while from what I know

 

oh...so how r u suposed to complete the dungeon? or u just can't?

 

you dont
