My Minecraft Realm has about 13 members. Ever since about 8-9 members, the members that were yet to join, when they did join were met with an INSANE speed boosts. The users do not show any potion effects, they are not affected by any command related to speed, and even after they are revoked and rejoin they are still affected by the speed. I have used a backup (most recent one as I do not want to lose any progress), I have downloaded the world and reuploaded it, and finally I have revokes all players affected and had them rejoin. This is causing myself and my friends to not be able to play.
