Everything was good befoe yesterday, now i am constantly desinc from the server but it works for my friends any ideas ?

More details : i spawn, open a ship menu and try to move power nothing happen, i can just but no interface and cooldowns, and when i arrive after the jumps i don't see the ship, only players floating in the air

These are all signs of a big network lagg. Check your/server's connection.

Also what version of the game are you using?

I am playing on 0.5 server, my friends don't have the problem, and my conection is fine (just tested 100/5ms 14ping)

So ? Game over ?

Well, if your friends don't have the same issue, then it must be something on your end.

Try the 0.7 version maybe, it has a bit better networking logic.
