The wallet often stucks on block submit and all future block submits with:

I have to run huntercoind with "while true; do huntercoind -daemon=0; sleep 5; done" and launch cronjob "tail -n 1000 data/huntercoin/debug.log | grep InvalidChainFound && killall huntercoind" every 10 minutes for temporary fix. Devs please investigate this bug.
