[reverses a change, possibly a bug, introduced on August 25]

From MaGog's logs for October 1:

I am glad to inform that the bug reported two days ago, whereby 149 game pages displayed inocrrect and partial bonus information, has been fixed. All 149 games now display the same information they did just before the bug occurred.

NOTE! CHANGED Surgeon Simulator Anniversary Edition [DLC], regional_str: AU,DE,GB,PL,RU, ***TO*** DE,GB,PL,RU,

Yay, the bonus information are back and it looks like we have regional pricing added and removed at the same time. As of now there is no price difference between US and DE for Hatoful Boyfriend for example. I wonder why they changed it so shortly after release!?

edit: grammar

Probably because of the Local Prices Update.

I wonder if the game versions will be re-added to the game pages at any point in the future...

I certainly hope so. If anyone notices them, please drop me a note.
