Missing 25% of my btc after a resync...
If you are having a hard time syncing (maybe poor internet connection?) , try getting all your private keys using the API command "dumpwallet" and then importing them into the Electrum wallet ( there will be an option to import private keys when starting a new wallet, and import private keys into an existing wallet). Electrum, available at https://www.electrum.org, will sync almost immediately since its an SPV client and you can check your balance.
