Hello, is it a bug in my game or the gate passcards intentionally disappear when I load the game? Whenever I save the game after I collect any card and then I die and then load again, I have all equipment, health, shields as i had when i saved, but the gate cards disappear... It's very disappointing especially in hell jail level and final-before-boss level... Sorry for my English

I guess, that's not a bug, but even planned to dissapear these passcard when you leave area/game (it was even written in message when first you picked up passcard).
This final stage is kinda endurance test. But don't worry - you can save before you reach top of the tower where final boss is "waiting" for you

This is probably an older bug that I couldn't get rid off entirely. But until this day I have not received any new bug reports about blue or red keycards that disappeared. Are you using the latest version of GG2 (1.11)? If not, please download it from the official download mirrors and the save game should work perfectly.

To Mike and Blue66:

I have the latest version and i have finished the game on hard, so it´s minor problem for me in fact. I finished both stages on second try. But it was weird when I saved the game to keep my progress, especially in the hell jail, and then i load it, but without the keycard... But i love the game (except north and marsh stages ) If i am only one to report this, the problem is probably in my computer
