Crashtastic, added the piston part in patch 0.4.8. Unfortunately it didn’t work very well. This patch aims to fix those issues.

• Improved stability by rewriting the piston code.
• Increased piston strength.
• Fixed several issues related to Piston placement in the editor.
• Changed the art for the piston
• Add ability to have multiple key binds per piston. This can be done via the tuning menu.

• Fixed a few issues with the editor for pistons and braces. You no longer need to attach it to two nodes. One will be created at the correct location.
• Fixed hotkey functioning when in the tuning editor.
• Increased joint strengths for all parts. Vehicles should be a bit more rigid.
• Added replay functionality to sandbox mode.
