Fractals are going buggy

Never seen so many bugs as I have seen during today's T4 run.Deepstone: at room with 4 orbs we all died. When we resurrected, we could not enter the puzzle again. Path blocked by black smoke like curtain./gg did not fix anything. We had to exit.Moten Furnace: end boss. The attacks did not stop for 3 minutes and the center target was unavailable to attack. We had to exit.

And this in only one T4 run.Somebody is playing with fractals and not doing a very good job at it.
