Hello my IGN is Dunebuggy8, some people may know me from my plot (Headshop, skin comp, and a series I do) other (and most of you) probably have no clue who I am. The day before posting this a got a permanent speed boost. I go I'd say 10 times faster then normal, I don't know why I have nothing in my inventory and no potion effect showing up. It's very aggravating trying to build with this boost. I have tried dying (In multiple ways), drinking milk, and countering it with a potion of slowness. None worked, I was wondering if a mod could clear the effect for me? It would mean a ton as I could then continue working on my plot. (I'll attach a screen shot). I play the creative section of the server. I don't hack, or any of that stuff. Any and all help is appreciated! Thanks in advance!
Nope, I've also taken out all the beacons and been in places without beacons. Yet the effect still stays.
Do you, or have you ever got a "book of death" or an "OP book" that gives you mega enchants? I think that may be your problem.
To fix your problem, put all of your enchanted items in a chest and drink milk, as what @Daddy has suggested.
Crash on walk: This is caused by items with an "Enchant" of a speed that goes over 5. Just don't hold the item. Most commonly spread Speed Crash item is a minecart command block.
try checking underground or maybe your neighbors? there are lots of problems in MV prison and creative especially with the creative hackers who crash ur game.
