• Parts are now added to the recent tray when selected, rather than when they are attached.

• Pressing left and right wheel turn buttons at the same time now results in no steer rather than turning left.

• Fix a visual glitch with long chains of ball joints.

• Fix a potential issue with generating copied part icon.
