@Alerum - This is issue is unrelated to the HoF mod. The problem is the Hall of Fame screen where you can see your past game results and watch replays.
@Cybah - I don't know how to help at this point. If I understand correctly, your own mod without BUG has this issue sporadically, so I don't see BUG being the culprit.
Some of the confusion stems from you making different statements at different times, likely about different games, but it's hard for me to know the exact sequence of what you're talking about. And as I said, I cheated a win and can see that replay just fine (along with all my older replays).
However, I do have a guess as to the problem. HoF is scanning the replay text lines for a specific notice to detect a win, but it isn't checking that it runs past the end of the file. Perhaps the changes you are using either a) doesn't put in a win message for some new type of win or b) puts in a win message that doesn't match what HoF is looking for.
