Just to inform you about a "missing" mintcoins observation during PoS:
I am using mintcoin wallet 1.0.0.
When opening the wallet and PoS mining starts, I noticed about 900000 missing mintcoins (should show balance ~2700000 but only showed 1800000).
I just had to wait a couple of minutes and the correct amount was shown in balance, so nothing lost.
Somehow it needs to read a certain amount of blocks to know the correct number of coins in balance (which is a bit strange imo).
The number of coins in stake did not change when the number of coins in balance got corrected...

Any comments from dev side?

This is reproducable.
