Best share still shows up with 1024 diff, or any diff.
That's just an S1 driver design issue. It happens when the diff is exactly a power of two and is harmless and cosmetic only but of course doesn't fix your issue.

Hoping you can help. I have a few workers on your pool. The
Antminer s1's are having no issues. However the Antminer C1's do no report "best share"
When I use them on another solo mining pool they report the best share however on your pool they do not.
Personally I would rather use your pool as I like it better, but I would like to be able to see my best shares so I can know how close I come to finding a block. A big fat 0 under best share is kinda disheartening even though as far as I can tell it is reporting shares.
