So I bought the Torchlight II 4-pack and it seems to be glitched. I dunno if anybody has mentioned it yet- didn't bother looking through the entire thread.
You're supposed to get 4 copies of TL and 4 copies of TL2- 3 giftable of each. I only got 3 copies of TL2- 1 for me, and 2 giftable copies. I got 4 giftable copies of TL- dunno if that's a glitch, or because I already own TL.
Looked around and it seems several other people have had similar problems. I saw something that said that the missing copy of TL2 will show up in you inventory after a few hours, but I'm not sure whether or not that's the case, so I still contacted Steam support.
