This happens to other players as well. Sometimes when I enter deathmatch either someone else dc's or I do. This first started whenever the deathmatch changes were made.

 

Does anyone know how to reproduce this or does this just happen at random?

 

Kuke from what I've seen it's really just at random. I know it has happened once to me but in the disconnect message it says that I was kicked for flying.

 

A couple other bug reports on the same thing

From what I've seen it is indeed mostly random.

EDIT:

For some reason I've noticed that it happens more to some users than to others. It has yet to happen to me, whereas it happens fairly reliably to others.

 

yes at d-match i always get kicked for flying or lagged out

 

Does the server ever kick someone for flying for, you know, flying? I think that the server kicking for flying could be removed because it causes more problems than helps.
