A bunch of miscellaneous small changes and bug fixes in this update, the main ones being:-

• After detaching a part from a construction, it now becomes selected rather than just dropping onto the floor.
• Added a “no control” mode to the motor part behaviour, in this mode the motor runs continuously when switched on rather than being controlled by player directional inputs.
• I (re)disabled free spinning attachments between gears and axles as it doesn’t play well with physics when the axle spins quickly (too unstable – gears wobble all over the place).
• Fixed a bug where part attachment intermittently doesn’t work during low frame rates.
