When was the last time you confirmed that you were on the correct chain?
Also, how are you confirming that you have really forked?

If you haven't resynced since last week with bantime of 50, your nodes would have forked last week when we had a network issue..
I have many wallets & masternodes and none of them has had any issues since the resync few days ago using bantime=50 in conf..

Just to be clear, being few blocks behind is OK and isn't due to a fork.
(it can take some time to catch up but it will eventually)
