Node error invalid_chain_found: Block, invalid chain found

[whphhg]

Both of my nodes that I'm using for creating and testing of the GUI started to log the errors below a few minutes ago.

After restarting for the first time one died with Segmentation fault shortly after launching. Now both are logging the above error and money supply is at 5 for some reason.

I've started a fresh sync and will report what happens.

It finished syncing and is currently on height 886,733.

I got another invalid_chain_found in the debug.log, but this time for [ERROR] - set_best_chain: Block set best chain inner failed..

I've restarted the node and it synced to the same height as the block explorer (893,064).
