After porting the savegame from live release to PTS, my savegame lost the Hard Mode status. The Hard Mode marking from menu disappeared, and the game works as if it was in Normal Mode - no cost for fuel, changing regions etc. However, in the savegame text file, the "isHardMode" is still checked as "true". The game rules however are reverted to be the same as in Normal Mode.

Additionally, after clicking the new function to edit game rules in "Load Game" screen, the game is softlocked - nothing appears, the available key options disappear and clicking anything doesn't do anything, the only option is to force game close.

As of PTS update 09.09, the issue still occurs

Update PTS 23.09. and the Hard Mode savegame is still automatically changed to normal mode. And the option to modify rules in the "Load Game" screen seems to be gone...
