Somehow the NavSphere is stuck pointing up, even when I try to disable maintaining heading. If I press lock prograde or retrograde, it works, but hte navsphere seems to wrestle with itself. Restarting the game and redownloading the beta does not help.
I have no clue what the initial conditions are, but this is what happened when it appeared:
1 Spawn in the Soyuz from my page (active)
2 press 1 to cause a launch abort
3 wait until the parachutes deploy
4 click on the booster that's still on the pad and blow it up
5 tap the navsphere to lock heading (disable lock retrograde)
6 ???
Good bug report. Thanks! This will be fixed in the next update.
