Hi, in some cases failed payments (e.g. receiving node is offline) are not cancelled automatically. Just ping me in any of the pool’s channels (Telegram, Discord, Twitter, Gitter, Keybase, or even email) and I’ll do it manually.

Regarding the orphans that another user mentioned… yeah we had some pretty unlucky days. But in the end math always does its magic and it averages out, so today all of us mining on the pool were very happy with today’s results:
