Yesterday I installed the make eventing great again addon. Now every time I join a server I'm greeted with this error message.
I also talked to my friend Temper who has the same addon but doesn't seem to have the same trouble. However other people such as Platypi also have the problem. I don't know if that information matters but that's about it. It's very tolerable, just annoying and should be fixed.
If you need any further info such as logs to help me fix this, let me know in your reply.
