Nengcoin has successfully Hard Forked on Block Height with Shallow ResetNengcoin (NENG) has successfully hard forked on block height 2655921. The last block that old wallet (v1.5.x version) can sync with v1.6.x is block height 2655920.
Please also note that after the hard fork, effectively Nengcoin had a shallow reset to diff = 0.00244. This is another boom for USB ASIC/GPU solo miners. The shallow reset is purely caused by hard fork, not a common type of reset we saw before.
See below block hash details on the hard fork:
