False positives during combat causing players to get kicked

[MorkaZ]

Describe the false positive and how to replicate it

1. Wear full netherite set (which reduces knockback a bit)
2. Do a random pvp movment related with pressing W S CTRL and Space
3. Get kicked

enable verbose

If you mean adding %verbose% to kick message then I just did it and pleased right now player for another test. Now I have to wait for results

This won’t be a netherite issue, I almost guarantee it’s the sprint desync

[SamB440]

And use the simulation template next time, you need to provide a grim log

[MorkaZ]

This is what happens before kick:

There is no grim.log anywhere

Also, this is kick message with %verbose% at the end:

Just tested sets - they do not matter. Same problem happens also in diamond ones.

[SamB440]

That's the sprinting desync.

That's the sprinting desync.

Good. Is there any chance for fix?

[SamB440]

Not on Grim 2.0, it was not designed to account for this.

[MorkaZ]

Wait, is there newer version?
Also, isnt it anticheat failure?

isnt it anticheat failure?

Just partially. It's Minecraft issue demo
