Piston extension limit breaking when reverting back to editor.
Steps to reproduce:
1. Take every piston.
2. Limit the extension.
3. Launch craft.
4. Revert back to editor.
After these steps extension limit just sticks to whatever value you set it to and completely breaks the part. It can even be done several times. The only way to fix that is to take a new part, craft reloading doesn't work.
