Crytek - come on - the spelling is even visible on product card...

Well, Crytek should fix this, but you should note one thing - GOG claimed it will be fixed "soon" A LONG TIME AGO - so by now we can assume GOG was lenient and possibly said something like "it's ok, no rush" and then Crytek set this to low priority. Or perhaps GOG even told them to not bother.
What I'm saying is the blame is partially also on GOG actually for not enforcing it.

Btw - kind of a huge necro you have done here - haven't you?
