I see this as scummy, i dont think its malicious but if the store page tells me i need to buy it even tho i own it from a bundle that could be seen as trying to sell me the game twice. i would realy love to get at least a warning on the store page like "Hey, u already own this bundle and it should be included in it". this way they dont have to acually add it to my account but if the store page looks for bundles it was included in, this could be fixed.
At least personally im not willing to pay for a game twice.
I also have no problem if it gets solved, by an add all button, im not conserned about cluster in my library.
All i want is that the store no longer tells me "In order to download this game you must purchase it at or above the minimum price of ..." in a game i purchased in a bundle.
