According to your logs, these errors occur when node is launched, on blocks which were already accepted to blockchain, i.e. passed POW (nBits) check once.

My best guess,  the MultiChain directory is corrupted.

Did you move or edited files/directories in MultiChain directory manually?

Do you see these errors on all four nodes?
