My QT Wallet just asked me for my PoDC auto unlock password.

I clicked cancel and my debug.log is filled with this:

2018-11-01 04:14:57 CheckForkWarningConditions: Warning: Found invalid chain at least ~6 blocks longer than our best chain.
Chain state database corruption likely.
2018-11-01 04:14:57
 ERROR: Found invalid chain with higher work (ChainState database corruption likely)
2018-11-01 04:14:58

 ** Erasing Chain and Rebooting Wallet Now **



I know this is Halloween and all, but what kind of witchcraft is this?
