recently i have been pvping and i get this bug where i suddenly cant hit people and i get kicked if i hit then and they kill me while i am in combat tag, its highly annoying and stupid.
No support, you are probably just block hitting (Anti cheat doesn't really like that) so it thinks you're hacking. Besides if the anti cheat is removed most likely you'll get bhopped and tp aura'd by hackers all the time.
