I bought Tyranny commander Edition Pre-Order on GoG, but for some reason its still showing as to buy and not owned in the games, but its there as Tyranny in my account games library?

Is this a GoG bug or something?

I think it's a long-standing "feature", where editions aren't taken into consideration. Like if you have the top-tier of a game, it still says you don't own the lower editions that are covered within the one you already bought. Something screwy like that.

Yepp, I have lots of games already like this. GOG should get their act together and at least mask the problem :D

A bug that occurs with games that have preorder exclusives.

Ahhh right, so because its pre order it will still show up in games to buy (as in not yet purchased) this could become an issue further down the line if it ever gets placed in one of those bundle things, you have the game but have to buy it again to get the discounts LOL i seriously hope they fix it.

Don't count on it being fixed. Same thing has been around for ages for kickstarter editions or for Witcher 3 and boxed or nvidia codes to just name a few examples. And they never fixed it.
