At me too, coins in a purse have disappeared. Received on August 1 and 2 ( http://xlc.my-mine.su) What kind of Copperfield tricks? Trifle, but unpleasant! (((
If you open the pool's webpage http://xlc.dark-mine.su/ you can read the following info:
2017-08-07: Fixed all pool links to blockchain explorer.
2017-08-05: Alot of work done. Pool fully updated. Ophaned blocks bug fixed. Payments fixed and enabled.
2017-08-04: Blockchain rolled-back to 22940 height. Also pool database rolled-back to same height. Payments disabled untill Dev's future instructions.
2017-08-01: Payments enabled. Check your wallets.
So if you got the coins after block 22940 they are gone.
