I had in my wallet 31003TEK, before the block 506500
After The first fix in old wallet :
and now I have Total Balance 34868 TEK
Have I lost my money or not?
Well, if I figure it right, it looks like you're to the good about (34,868 - 31,003) 3,865 Tek. If correct, this would mean you have not lost your money.
Are you implying that there is some kind of chicanery going on in the updated wallet?
