Describe the issue

Step works going up one block increments in a teleport-like fashion, without generating any VL.

How to reproduce the issue

I've used Wurst (Both legit and simple), and have been told Sigma works as well.

Extra links/Videos (Including debug logs)

Any possible config options changed or plugins that may cause interference?

Default configuration.

I don’t recall changing anything that would effect this, I’ll have to take a second look though.

Thanks for reporting.

I have confirmed it to be the same prior to any changes made on your end (b1149 and b1139). Sorry for not mentioning that earlier. It is a general issue with NCP.

The client is speeding up/sending a very small burst of packets to simulate a player jumping. This would be a bypass of the MorePackets check than SurvivalFly, which was originally thought. I may rework the MorePackets check just because the false positives it produces and the protection is somewhat limited. I just need to take a further look at a good detection method and what exactly the client is doing.
