Temporal sanctum desync?

Hello,
I am currently having an issue when running the temporal sanctum dungeon, every time I run the dungeon I get what looks like extreme lag/desync and the game becomes unplayable I can move around use abilities but no mana is consumed no monsters spawn and cannot progress.

same brother, been happening the past 3-4 days and actually making a single legendary is a whole day process. really hope it gets fixed soon (or just acknowledge at the very very very very very least) cuz my motivation to play this game is RAPIDLY declining
