Hi everyone, sorry for the delay in response.

@AngusCanine curious if you submitted a support request as I didn't see anything come through. I will be looking into this today and double checking the email servers etc

Regarding payouts, it seems that a block was found on December 31, 2016 and I have noticed that the block reward is only 12 and not the 12.5 that I have the software set to.

I was not aware the block reward for zcash could vary like this and most likely the payout failed when it tried to payout 12.5

I just got back from holidays and will be digging deeper into this today Will keep you updated
