There's nothing to fix per say, we're analyzing the situation as PoW subsidy halves and PoS block frequency increases and takes over the blockchain, as planned.  Once the PoW subsidy reaches the baseline .01, it will be extremely inefficient, since PoS blocks overrule PoW blocks.  But the plan from the start was to have CB PoW fully mined and running only on PoS.  We have several plans ready to be implemented to assure a lower bound in the PoS block frequency so that we can guarantee the transactions will move.  Other than that, these are just growing pains as we analyze the behavior, use testnet on the side to continue to experiment with development ideas, and eventually we'll have the tweaks so that the blockchain is in the sweet spot.
