debug stick and lever arm - working?

I have not tried to check this in other versions.
If you put the lever, and try to turn its debug stick, then unfortunately it will not work. I try on the 15th version, and on the snapshot 1.16 of the last - it does not work. Either I don't understand something, or it's really a bug. I hope to fix it. I discovered this when I wanted to make a homosexual leverage.
