Bug with achievement "Who Needs A Mechanic?"

OS: Windows 7
Version: 1.01-11100

After beating Zone 42, "Consumed King", I immediately got the achievement for not using mechanical blocks. The thing is, I did use mechanical blocks, namely two pistons and a grabber.

When I looked to see if anyone else had this happen, I found another post here back when the achievement had a different name (http://forum.spiderlinggames.co.uk/index.php?threads/achievement-i-didnt-need-gears-anyway-bug.6769/) that apparently found out the achievement checks for armor blocks instead of mechanical blocks, so that might still be the case.

Attached are the file for the machine I used, as well as my output log.
