When in spectator mode, in a server, when you scroll to increase your speed to a certain level, you'll tp back and a server message pops up:
PLAYER moved too quickly!
Steps to reproduce:
go to spectator mode
scroll all the way up to increase your flying speed
fly as fast as you can and see yourself get teleported back
Also appears to happen when sprint flying in creative ~fixed

Yes, I also experience this.

Can confirm for 42a

@unknown you can't add versions other than the current snapshot/full release

FVbico I know, I was looking at the history and saw you asked for someone to confirm it for 42a

@unknown that was quite a while ago, and as you can see, I removed that comment a while ago as well

can a mod please update the confirmation status?
Edit:
Thank you

I don't seem to be able to reproduce anymore, anyone else still have this in 15w50a?

Still happening for me in 15w50a. Weird.

@unknown, mind keeping it updated then, I can no longer reproduce this
Can also confirm 15w50a

Hm, I tried this for 3 minutes straight when looking if it still occured, no results, perhaps if I try again today

again tried this in 16w02a no "moved too quickly" at all, anyone else still able to reproduce?

No "moved too quickly" but I still get the tp back. Happens with Elytra and scrolling up in Spectator mode, on a server.
Edit: Also console says player moved too quickly! with co-ords.

ok, so it still occours

Resolved to MC-90062 since that has a lot of duplicate / related to links.

ok
Confirmed for 16w04a

@unknown this isue is resolved as duplicate of MC-90062 due to the amount of links it has
can anyone confirm?
