I was doing some playing around with your mods and quickly discovered that the wires are bugged.

After red alloy wire or insulated wire were turned on, if they had more than 1 wire, they would not turn off again without updating the wire as shown in vid: https://youtu.be/mh4jUPtRGxE

Did some further testing and discovered that this problem is new to the latest version; did not exist in pre11.93 version.

Lol, major derp on my part. Fixed with c9e29a7.

Yeah, same. Thanks for the fix!
