Nemesis Enforcer Unlock disappeared after relaunching

[Pumamori]

Good day! This might be unrelated to the mod itself according to the modding Discord, but for completion's sake and because it bummed me out I figured I mention it just in case it is related to the mod and something that can be avoided for others!!

I unlocked Nemesis Enforcer yesterday (played on Monsoon, stabilized Void Fields, got the message, killed him after Mithrix at the ship), that worked fine, my friend who wasn't playing Enforcer also got him unlocked in case that's unintended (though I reckon it's just killing the Nemesis Enforcer?).

I tried them out in Singleplayer afterwards and it worked fine (super fun moveset!). Today I launched the game again and the unlock disappeared - both the challenges and the characters.
