The 3 december i have withdraw 549.765 PAcglobal from graviex. In the same day i have send 150.000 pac to stakecube address, and i see 399.765 in my wallet.
today i open wallet and see balance 0 and a incoming transiction MINTED from 7 december with 0 confirmation. Later this transiction, all my pac disappered. Why ?
this is my address
http://explorer.pacglobal.io/address/PTRtsckgse21ZgjtLqAjeM2qgCcNvmxZW4The sum of PAC you have has simply staked. If the transaction with 0 confirmations has the status "0/confirmed, not in a memory pool" you can simply right-mouse click it and select "Abandon transaction". That should recover the funds (provided that your wallet is otherwise doing fine).
If you need further help, you can also join PAC discord server so one can chat with you (and exchange e.g. screenshots if desired).
