I saved my game results over a month ago.
Today, after checking the chain, the results did not match. This happens at certain parts of the chain.
I assume there's some sort of misunderstanding, if you provided more information (e.g. what was it before, what it is it now, what is the game, etc.) it'd be a lot easier to help you.
Each game is verifiable immediately after it ends, and there is unambiguously only one possible hash chain (that's what the published terminating hash guarantees). So it's simply not possible for the hash chain to change, and especially not parts of it
