MC 2.0 stopped working (don't know what was done before, but it was not running for a long time).
I am not able to start. The following error message is provided:
Error on starting daemon: multichaind: core/main.cpp:2213: bool DisconnectBlock(CBlock&, CValidationState&, CBlockIndex*, CCoinsViewCache&, bool*): Assertion `pindex->GetBlockHash() == view.GetBestBlock()' failed.
