Minor bug: If you add a privkey to the wallet and try and solo mine, the miner starts randomly freezing and not submitting work units anymore. Was fine for ages before the privkey, started  glitching quickly right after, happens in minutes a lot, and most times right after finding a block. Moved back to pool mining for now due to it, and the miner is having no issues, soon as I go back to solo it starts freaking out.

Edit: I've done a reindex/rescan still happens within minutes of starting the miner for solo mining. speed freezes and it just doesn't do work anymore.
