Bug: Ritual in boss room in Lookout map deleted door

Just did a lookout map, and the boss room door seems to be gone after the ritual ended.

(also delirium was ending, had timer, when i entered the boss room in case it's relevant)

How do i report this?

Not the biggest deal, but lost all the stuff i skipped keeping up with delirium. Polished! =^)
