ok, so I have trouble saving bitcoin for the future so a while back I made an address on my core wallet and then dumped the private key and saved it on a piece of paper.

Now years later and I hand typed the private key into another wallet and it did import a wallet but its not the same address and the balance is 0.

I check again on a new version of the core wallet (not synced) and I dumped the private key for that address and again the private key that is dumped is not to the address with my coins.

How is this?

Any help would be appreciated.
