Yes, it's a very odd question, but it's one that has me scratching my head.
I stopped playing the game for... a while. When I came back I needed to check to see what Adventure Packs I owned, and looked at which guest passes I could purchase to do so. Ruins of Threnal was, and still is, among those guest passes. Today I finally got to level to play through Ruins of Threnal, but when I went to travel into the Adventure Zone I got a premium content advert instead. This was confusing, so I checked which adventure packs I could purchase and to my surprise saw the Ruins of Threnal there... while also still seeing the ability to purchase a guest pass to the Ruins of Threnal as well.
So now I'm just completely and totally confused if I even own this content. Email records are incomplete from that date and time, otherwise I'd know for sure if I had purchased it or not. So other than saying I think I stopped playing the game sometime around early 2012, I don't have much I can say to assist. Apologies for the lack of help.
Ultimately it's OK if the answer is "No, you do not own that content." It's been awhile, the game changed development studies and records may have been lost. But I need to know if being halfway flagged for Ruins of Threnal is going to create problems for me if and when I decide to repurchase the content. Last thing I need is for me to hit the buy button and have half my store content disappear on me... or get flagged as a free account again.
