Launch controlled rockets not landing properly client-side (relog fixes it)

[EoD]

I just launched to another launch controller. First there was the typical rocket breaking manoveur, but when I arrived it seemed like I had a lag and ended up a bunch of block below where I was actually supposed to be.
The rocket was gone, but the launchpad was intact. That's what the server had to say:

I forgot to relog and see if it fixes any problem, sorry about that.

I just had this exact same thing in 1.7.10, but on a spacestation.

I just flew from the overworld using launch controllers to my space station. It was in its landing maneuvre but when it encountered the launch pad it just phased through it and I ended up at y coordinate -7 without a rocket.

When I later flew back to the same space station with a new rocket, the exact same thing happened, but then both rockets were on the launchpad.

Oh, I can reproduce this very same with @Solestis is describing, although I ended up in y=-90 or so. After logging off and back in the rocket reappeared on the launch pad.

You get +1 like for "typical rocket breaking manoeuvre"
