Rubberbanding and hard crash during Tridolon

[ProbablyGeorge]

During a Tridolon, I kept rubber banding and occasionally couldnt cast abilities. Right at the end, as captured the last eidolon, I was stuck in place, completely unable to do anything. Couldn't archwing, Kdrive, go in op mode, /unstuck did nothing. When I died and respawned, the game bricked, and I had to open task manager to shut it down. I lost out on all the loot right at the very end.
