tl:dr -- doesn't seem to be saving the 'mode' setting

I have AB's sending to banks of pulverizers/furnaces, usually have ab's set to round robin to spread things around, however, after quitting/reloading world all the ab's are set to greedy

this may affect other buffers/extenders, hadnt noticed/tested those

Thanks for reporting! Fixed in release 1.0.7c!

sweet :D
