This isn't just happening in Sol, it seems to be in all systems. I've had it happen to me a few times and the only way to sort it out is to land and repair, sometimes even log out on the planet then log back in to stop it (as even multiple land and orbits hasn't cleared it).
One time tho, I was in a squad on Lustra in an 'engi' and one of my squadmates had to orbit. We were both at an 'e' field, and I saw him leave - but as he left the planet his ship just hung there a few feet above the ground. I thought he had crashed, but he was still active in chat, so I told him I could still see his ship, yet he confirmed he was infact in orbit.
Next thing I read is that he is getting shot and as he is now in combat mode, he couldn't log out or land... he was stuck - taking damage.
He was in orbit - yet I could still see his ship a few feet above the 'e' field, there was a Parasite and a Rocketeer shooting him, I watched as the rockets travelled upwards towards him. I then thought, well if they can target him - so can I, which I was able to and I healed him from the surface while he was in orbit (super engi skills

). I killed what was attacking him and he was able to log out then (with full health).
