I hope you know that the electric wrench has a potential to reduce advanced machines into machine blocks...
You can change it to lossless mode (hold M and rightclick to swich modes). If you did that, then sorry and hopefully the bug will be fixed...
I didn't know that, thanks for the info. I just had an extractor turn to a machine block and came back to this thread. The mode was the issue.
Suggestion to dev: Make lossless mode the default. That way, those that know how to change the mode also know that there is a risk involved
