This keeps happening to me everytime I join a world it says that, and I cannot invite anyone, neither can I join servers or other people's worlds, however I do add alot of add-ons and mods ect to my minecraft which has slowed it down alot but I do not see this as the cause, since I've been doing this for ages now, I make maps ect. This issue is reall annoying and it hasnt been patched for over a year. Please fix this.
