Good to know. I'll put 3.0 back up for GOG users.
Thanks for the heads up
@ebmar: yes, almost everything the player sees when they aren't in a menu is mipc28x6. Since the Aspyr release fixes the gui stretching in the steam version, there wasn't anything to do there in v4 besides fix that one hover description element. Overriding the 3.0 version will basically just give the player the vanilla GUI.
