It seems that too many clients are still on the old version and some miners may have stopped the correct fork from taking over if they were on the wrong one.  We would recommend loading your miners on the p2p pool as we know this one is on the correct fork and try to get the coins back on track.  There will be thousands of lost coins in this process but it will stabilize the network if successful. 

On another note we already have a backup plan in progress to fix everything as a safety net. Just make sure to follow @FuelCoinNEWS and @altcointoday on twitter.
