What are ya'll using the .conf with just connect= or the .conf with addnode= ?
I have 2 wallets that are using each and after deleting everything, including your wallet.dat(after you backed up), I am on sync with both .conf files.
I left the wallet to update overnight with the connect=. Checked it this morning, before I loaded my wallet and I was out of sync according to the blockchain explorer. I reloaded my wallet.dat and changed the config to addnode, but it made no difference. I'm now 25 blocks behind, but no sync errors on the wallet. It is updating though.
