What happened here?

[Begi1982]

I rarely check the state (once a year) of my chia farmer, but I did it today.
It showed me 2xch 2mojo. I tried to verify it on the blockchain explorer, but there was nothing.
I deleted the wallet db and restarted everything and it shows me 0 xch, however at leat 2 mojo should be there as far as I know.
What happened? I received those mojos at a promotion. I miss them.
