1.0.900 - Job hangs up

After upgrading to .900 my previously working plugin stopped working - once it starts a job it seems to hang up in waiting mode (UI shows that spinning icon), and if I try to click on On or Off button again it says “wait until previous command executed”.

Have you guys changed something about handling jobs?

???

as mentioned in many threads, would be great to see the changelog!

Fixed in .906
