I was checking out stuff with the coreprotect command /co inspect and I noticed an item with the id:166. I was curious and typed in /give (myname) 166 1. Immediately, my client throws up the error screen which says: Internal exception: java.lang.NullPointerException. I tried restarting, redownloading the launcher and its files, restaring my computer, restarting the server (I'm the owner). I still cannot rejoin my server. Everybody else can, but I, the owner, can't. Everytime I try to join my server it says Internal exception: java.lang.NullPointerException. Please help. I only have one other staff member available, and I can't work on all the crucial stuff going on in my server. I need a fix ASAP.
