Hello. Last week i was reset from Red 100. I had a backup which took me back to Red 98 so all seemed fine. However, i lost friendly fire mutator which i use a lot and i'm not sure how to get it back. I have followed advice on these forums to make things unlockable again but i had no success. Let me explain the timeline of events that led to me losing friendly fire and hopefully someone out there may have a solution.
Day 1 - Ranked red 98, made a backup.
Day 2 - completed 4 player campaign co-op, unlocked friendly fire mutator and got the achievement.
Day 3 - Played beast, game froze, got reset.
Day 4 - Used my backup to get everything back except friendly fire is locked again. Checked campaign and it says i have played all chapters in 4 player.
I had tried the advice in one of the big reset threads that is supposed to make things unlock again after a reset, the advice that says to move player data and gamer profile to a memory stick and remove it on the "press start screen". This was supposed to make the achievements and collectibles appear blank but it didn't work for the collectibles. It says i still have them all. I then went and played the whole campaign in 4p co-op again in the hope it would unlock FF again but it didn't.
I'm not sure what to do now. Since i used a backup that was made before i unlocked friendly fire and have no way to remove the achievement associated to it, is it permanently locked now ?
