The Chosen Ones

Originally, I have 422 gold. Selling Lucky Clover should give me 225 gold and the total gold I have should be 647.

When i sell it, it show +225 in the screen, but total gold is only 467, which increase only 45 gold.

I found this problem in version 1.7b and now I try with 1.7d but still get the same problem... I try with different item and different shop , but the gold return is very different with the selling price label in the item.
