The Architecht bug, crash = kick with rollback

Just had this happen, for some reason the Architect threw a million chaos bouncy balls when I cursed him and hit him with the Annihilation effect from the Hayoxis fulmination. The balls slowed down the game, my pc was fine, nothing else lagged. The game gave up after like 10 secs and crashed. When I logged in again ALL my items I had picked up in the temple were gone from my stash (A gauzewrap for instance). But, it still automatically closed the dungeon and destroyed progress. So this seems like a really weird interaction, I didn't die, I just crashed, shouldn't I be able to come back and continue the fight? I guess the Server hated those balls and couldn't decide what to do.

TLDR, maybe the bug is with his chaos balls interacting with the Hayoxis Fulmination effect?
