After the latest update, I find that a drone is nearly always placing itself at exactly the same position as my character, stopping me from moving. Every couple of seconds it teleports a few tiles away then races back to my character to stop me from moving again. Occasionally it will escape this bugged state and instead just follow me really closely (1 tile away at all times) but then after repairing something it will again stop me from moving.
The problem does seem to be related to repair packs. When the drone is doing this it always has a repair pack on it.
