I kind of messed up the Steam import last night, so if you got a big long email that says all your games were re-imported, I’m sorry. Grouvee normally ignores games that are already in your collection for a Steam import, but I messed that up yesterday.
It also would have added games to a Played/Backlog shelf that you might not have wanted. Again, I’m sorry, and I’ve reverted the screw up in the code.
If it screwed up a lot of data, email me at peter@grouvee.com, or just PM me here on the forums, and I’ll see what I can do.
