I left for Osaka for 3 days and came back to this on my wall in my room only. I left the bedroom door open to my whole house. I’m pretty sure it’s mold. Is this treatable with a drywall patch or something I could grab at Vivahome? I’ve tried wiping it with mold cleaner but nothing. This morning I think it grew a little bigger as it had a faint surrounding ring.
