On the 19th, that was the date that the coin Forked due to a bug in the PoS code. Therefore all the coins mined on that date wouldn't have been valid. This was not an issue with our pool.
Is that so? I receive my coins (early 19.7) from dwarfpool with some delay. I can printscr my wallet if you want. And why you don't answer to my email? Great support.
