I decided to start shaking Mangocoinz when I was on the sh#ter I made about 0.3 then decided to hook up the wifi and sync it up, I lost all that 0.3 for some reason after sync and was mining on the latest wallet 5.0b...
This has happened to me too. Though, i've never had the misfortune of screwing up from shaking it while on the toilet. I was shaking it on my bed and prematurely lost my payload while trying to sync.
