I noticed when trying to add
Red Storm Rising in my profile under my favorite games listing (by clicking on Add to your favorites link in the game review), when i look into my profile it has added :
Last Half of Darkness instead.
(i tried the opposite to see if it added RSR , but adding Last Half of Darkness from the add to your favorites adds a second time Last Half of Darkness).
I removed them both from my profile (at least it worked).
Not an important bug, as but in case it leads into something bigger, just pointing it.
