Thanks for the quick response! So to be clear, I can do the factory reset and once it's complete, have full functionality back with my existing wallets?
Factory reset nukes your DB, Core's blocks and defaults your settings. It doesn't touch wallets nor lockboxes.
Any idea what would have caused this?
Core is either missing a block in one of its blkXXXXX.dat or the block got mangled and the valid one was written after it. Core does not delete mangled blocks nor overwrites them. Armory is chocking on the mangled block (it's probably not mangled enough for Armory to just skip it). The upcoming version handles these kind of cases properly.
Ok, thanks for addressing, and that makes sense. I did the factory reset over night and it just completed, but again it's stuck at block 191534. It sounds like my options are now:
1) Wait for a newer version of Armory (acceptable if coming out in the near future), or
2) Re-download all of the blockchain in bitcoin core and then rescan in Armory.
Anything else you can think of?
EDIT: To be clear, I did the lightest option factory reset. I guess a heavier version is also an option.
