Well I waited for some time after sending sdc ->shadow before sending shadow->sdc to a new stealth address. This is after reading about 10 block maturity comments etc. This time it worked beautifully. However my first shadow which I tried to convert back to SDC is still missing in the ether. Seeing that I have a successful conversion this time I will write it off as fat fingers. However if it is related to the '10 block shadow maturity' statement in earlier posts, it would be prudent to prevent any conversion attempt pre-maturity in code to stop this from happening. I will try again using 'impatient mode' to see if I can recreate the issue. Still : great work. Massively undervalued. Which is great for us here atm (;-)
