Well that upgrade didn't go so smooth for me this time, but all is cool now.
Ran the upgrade, downloaded from wallet then closed wallet and ran the update file, told it not to import the blockchain since I was synced before the upgrade. Upon restarting the wallet, it got stuck on scanning the blockchain I think it was.....waited a few minutes before I closed it to reopen, then it came up with corrupted wallet.dat, unable to salvage. It created a .bak and new wallet.dat file.......I let it download fully at this point.
Once done I restored a backup of my wallet file, it came right up but was missing the stakes from the last 2 days. It of course immediately made up for this right after unlocking, but I don't understand why this would have been lost as those transactions should have been stored in the blockchain.......well, I think anyways....no expert in this area.
Anyways, all is good now just thought I would share my experience.
Thanks for the details!
Installer automatically rescans the wallet (without downloading blockchain) after every update, so if you gave it some time, it would open after rescanning. I recommend not to uncheck "import blockchain" because installer would do the backup of your wallet.dat while importing the blocks. I noticed low network weight today and thought that you were disconnected. But our nodes were at the same right chain, so I wonder which nodes you were connected to and why. Anyway we modified checkpoint system for more stability.
P.S. If won't have to run update anymore, now it runs automatically after you download it.
