I followed the guide here,
When I got to the point of sending my newly mined TAZ to my newly generated private 'zaddress', I encounter a crashed. I was however sending three other amounts to that same zaddress at the same time before waiting for the first to complete, I had others queued.
Now when I try to start zcashd I get this error,
zcashd: wallet/wallet.cpp:605: void CWallet::IncrementNoteWitnesses(const CBlockIndex*, const CBlock*, ZCIncrementalMerkleTree): Assertion `nWitnessCacheSize >= nd->witnesses.size()' failed.
Tried a full restart, same.
