Thanks for reporting this. I have to say I've never used Anticheat but I'll see if I can reproduce it. It seems to have to do with the slow speed setting when you are in last stand; did this happen with the default setting for speed, or did you add your own value?

Yea default configs, Anti cheat is widely used to combat Nodus (Main known hack client)

@SPaRTaNMaDNeSS: Go

So I wasn't seeing this before because I was always op on my server, but when I deop myself I see it exactly like you've reported. I tried the last two versions of AntiCheat; in their latest version they fixed a problem with soulsand causing almost this exact problem, and I looked into another anti hacking plugin and they have the same problem with false positives when walk speed is set super low. I guess no one cares about people hacking themselves into slowness...

Anyway, the problem seems to go away if you set walk speed to 1.2 or higher in the LastStand configs. Unfortunately there are still a lot of false positives on soul sand in this case. It's not an ideal solution, but I can't find any other way to deal with it on this end :/
