Fixed the problem by deleting testnet3, forgot about the wallet, lost my coins
Then again, if the problem was with the wallet as it seems, at least I don’t need to worry about this anymore (unless it happens again…) I’ll be backing up my address keys from now on!
@daira and @str4d if you haven’t resolved the issue with error on startup: Assertion `nWitnessCacheSize >= nd->witnesses.size()' failed. · Issue #1378 · zcash/zcash · GitHub and are curious what commands occured before the error occured, I’ve provided Simon the testnet3 folder. Basically, I was moving mined funds to protected addresses while the miner was still mining. I shut down the computer and rebooted. Then I tried to restart the daemon and got the … ‘Assertion `nWitnessCacheSize >= nd->witnesses.size()’ failed’ message.
