This happened to me on PC. When one of my alts leveled up, she got the Room to Spare quest (I think this is level 20). I was surprised, as I thought she had already completed the previous version of the quest (A Friend in Need). Since this is on PC, which I don't play as much, I wasn't entirely sure. I had another alt reach level 20 not long before her, and she didn't get the quest starter from level-up (this was pre-Greymoor).

So, I assumed that this alt hadn't yet done the quest. I accepted it and went to the Snowmelt Suite. Sure enough, she was there waiting for me. I completed the quest and entered the room, then I logged off. But when I logged in with my main, it wasn't in my collections.

I don't know what the prompt was when I entered the room, as I didn't look closely, so I don't know if it said "open" or "preview." And, I didn't check to see if it was added to my collections.

Oh wait...I do recall that it asked me what permissions to load for the house, so the game was acting like I just acquired it.

I submitted a bug report, but didn't open a customer support ticket, since I already bought Proudspire and don't really need the inn room. I'll pick it up at some point for 6k.
