Hey guys found root of the problem, 1.6.5.2 change in stake splitting was too aggressive for the number of actual staking inputs on the network currently, so coins are being staked too fast and then sitting for maturity and this is destabilizing blockrate which destabilizes difficulty and caused forking.  1.6.5.3 will be released today with good stake splitting parameters and longest chain will be connected to automatically when the wallet finds a node on it once the blocktime is equilibrated, or you can reload blockchain to get on longest chain quickly.
