Yeah, sorry for the long delay. A few days after I made that post my internet connection went down and it took 2+ weeks to get it working again. I am still catching up with things and this one slipped through.

I'm gonna re-test the plugin on 4.1.11 and I'll follow up with 2 peoples that reported 2 different bugs but never provided me the steps to properly reproduce them. If they don't reply within a couple of days I'll release the update with only this fix.
