Oh well, it's happening only when I'm the host(not dedicated).
when i've joined another server it doesn't happening.
Just try to jump + fly together up, then open the menu

then u close the menu and keep clicking the flying key and u would get boost up oO

hm, so you can actually get non-dedicated servers to work? i thought nobody had gotten one running yet

That's also possible in 1.2.1. Doesn't this only happen when you're offline?

Guys, he's not saying that he's played on someone else's non-dedicated server... He's done it at his own server, and it's worked.. He's tried it at some of the Beta servers and it didn't work. So yeah I guess it's only possible to do it offline.

well, it was actualy online when I hosted.
so I have no idea if it happends as well if someone is connected to my server \ others can use it on my server.

I managed to put up a non-dedicated server, and so did Amblin. =\ We don't seem to have any problems whatsoever.

Hm, yeah it's an old bug I forgot about it.
