Not sure how to go about fixing this
Error while compiling ServerRewards: The type name 'EncryptedValue<>' does not exist in the type 'BasePlayer' | Line: 1875, Pos: 33
Have you tried removing the plugin, keep your data and cfg, but put a fresh download of the plugin back in?
I only suggest this because so many other people are not having that issue, that maybe just a fresh file could do the trick!
