No its not just you. Multiplayer has been the single biggest problem throughout Alpha - and doesn't seem to get too much better with each iteration (IMHO). I've seen the usual CTDs, lagging ships and invulnerability problems tonight that have been there since 2.x, and the disappearing/reappearing/jittering/pad-changing stations that have been there since 3.x. Not to mention the huge lags on exiting super cruise (seriously, longer than 10 seconds wait and drop us into a single-player instance, please?)
I get that p2p is extremely difficult over the wild, unregulated internet, but I do wonder how much nearer to a functionally complete, classic single player experience we would be without the large wing-spanned seabird that has been dangled around the game. But in the 21st Century everything *has* to have multiplayer.
