I lost to Audrey, and upon returning to the Abyss base the rain and thunder from the previous route seems to have followed me into the base. It is carrying over multiple rooms, but other than that isn't affecting gameplay.
Bonus you can walk into the 3 tiles next to this warp in the Abyss base.
Edit: Changed to minor bug, as now I have to deal with permanent rain for the Audrey boss fight! AND SHE HAS ALMOST ALL WATER POKEMON OH GOD DOUBLE HARD MODE.
Edit 2: Walking into route 10 and out fixed the glitch
