watch your if...
It says that if the "block height" is greater than or equals the "fork block height" then do something:
if (pindexBest->nHeight >= FORK_HEIGHT)
That something would be to do the reward times 100 (was 1% will be 100%):
nRewardCoinYear = nRewardCoinYear * 100;
I honestly don't see anything wrong there. (Does not mean I won't keep looking)
