I've basically given up.
Lost several thousand coins after cashing out from hashing.it. The coins never showed up in the wallet, and the transaction history shows confirmed on the pool. I've deleted my blockchain and redownloaded it but still, the coins aren't showing up.
You probably cashed out while the pool was on the wrong fork. Check your transaction history on the pool to see if the blocks are shown as credited to your account. If the pool was on the wrong fork and is now on the right one, the coins from the forked blocks will no longer show up in the pool block history.
