I have also had this issue when trying to drop my satellites off in keostationary orbit once I drop the first and switch to it to circularise after switching back, dock mode is enabled and I can't change it back or have any control of any vessels
No target information is shown on hud when trying to dock or rendezvous, can only use map mode to monitor target distance, etc. Can't see the target at all until right next to it, this makes rescue missions really annoying as I am doing them completely in map mode.
Autostrut also doesn't seem to work and fine-tuning maneuver nodes doesn't work either
