Can't access collectibles or classic maps

[CedZ]

I found all the doomguy figures and classic maps up to the first hell mission but now i can't access them in the main menu and when i go back to a level to collect them again they are already discovered. I think it's because i allowed access to my steam library for my dad's account on my computer. When i went back to the game the first time, a message appeared to tell me there was an error in my save files or something like that.

Did this happen to anyone else and is there a solution besides starting over from another game slot?

This exact thing happened to me. I did the same let someone play with my family sharing. Such ♥♥♥♥♥♥♥♥. Really wishing I didn't pay full price for the game. I spend sooooo much time looking for all the secrets only to have to unlock it again.

Same. It's the "developer mode" bug you can read around. I finished the game. Replaying missions for collectibles and challenges won't work (you will get the map completition but not the bonuses they shuld give like the models in the extras menu or the classic maps). I didn't share my account using family sharing, problem popped up after a crash :-s
