    @Taffelest, one of the server files are corrupted. I'm guessing it's the usercache file, but there is no way for me to be sure. Tell your friend to delete the usercache.json file from the server folder and see if that fixes it. It will regenerate.

    I'm going to have to complain to the spigot team. I've seen so many threads with usercache corruptions lately.

    He has no usercache.json file... wtf :confused:

    Okay, I got it fixed. Thank you for your help!
