There were some issues with bouncing back to the previous coordinate if you used a jumpdrive (anticheat got triggered).
That was some time ago though, maybe i should test that again... 👍

Are there cheats for this server ?

Hehe, you wish... (i hope not)
The anticheat messed with the jumpdrive/teleport operation, so i disabled it.
I see if i can re-test if that works again with anticheat enabled...

it was the "moved too fast" anticheat by the way...

Of cource not. With cheats it`s so senselessly and it is not honest.

Before this issue i have not thought about it. I was wondered.

If not, maybe the mod can increase the speed monoid to a very high value (dependent on distance jumped) for all players around the jumpdrive before jumping?

I think we would also have the "player moved too fast" problem with anticheat with travelnets and telemosaics, right?

Sounds like a good idea if everything else fails...

As far as i remember the problem was that a player clicks the engine "jump" button and starts to walk away after that, somehow the server got the events mixes up and the player seems to have moved in the original position after the jump to the new position...

Disabling anticheat is a pretty critical thing...
You can theoretical dig any blocks as fast as you want anywhere in the world and teleport wherever you want to go to even if you are dead. Of course the Minetest-Anti-Cheat is not the best, but it at least blocks the most malicious things.

What about attaching the player to the new position for a short time?

As far as i understand this is not quite true, some anticheat mechanisms are still in place:
We have a #audit channel in discord for moderators that is filled with cheat-messages:

Player 'xxx' triggered anticheat: 'interacted_while_dead' at position: (6812,12,22837)
Player 'xxx' triggered anticheat: 'interacted_too_far' at position: (-2545,245,563)

Still true, it is re-enabled, lets see how it works... 😏

Yeah, seems just like you only disable the moved_too_fast anticheat.

Recently I noticed that after jumping, or even just using travelnet, my avatar keeps getting tp-ed back to origin after a couple seconds. Not every time, just often enough for me to notice.
Probably during lag-spikes.
Possibly related?

I've noticed that when just moving around (usually just during lag spikes) I will get frequently teleported back a bit
I was wearing lava boots but I don't think I was sprinting

Possibly related?

@SwissalpS most likely yes.. 😞

I will get frequently teleported back a bit

I think i'll disabled the anticheat setting again, there are lots of false-positives in the audit channel on discord and the benfits are not that much...
