Can anybody replicate this issue? I noticed within the video, the client is injected already with Gepard Shield and most likely Hercules Emu there already has the codes as well. Those factors can affect somehow, maybe a clean client and Herc is better to test.

With Gepard or without Gepard the issue still exists.

I think this is in relation to a decision to combat position lag, while it's possibly true that on official servers the server software doesn't ensure this delay and thus doesn't apply any. It's also true that this delay does exist on the client-side. Resulting in "position lag" / desync. If the intent was to introduce a delay, and it's only enforced on client-side giving players the illusion that you "should" be able to move, then probably for the best to have one on the server-side.

I'm purely talking from memory here though.
