Dev, have I fixed it? Please see below:

Solution to fix "assert failure GetNextWorkRequired":

main.cpp lines 923-926 need to be replaced with the below:

const CBlockIndex* pindexFirst = pindexLast;
for (int i = 0; pindexFirst->pprev && i < nInterval-1; i++)
    pindexFirst = pindexFirst->pprev;
assert(pindexFirst);
