I was not presented with a 6 on that move. The list of moves shows a 6. The graphic shows a 4. I don't remember whether I got a 2, 3, or 4. I thought I remembered something lower than a 4, but I'm not sure. Certainly not a 6.

That is weird. If the database records from which the game is reconstructed have only one value for the die roll, then the program doing the reconstruction must somehow overwrite the correct value, just in this one move in this one game, in the move list. Or the database stores the die-roll-as-graphic separately from the die-roll-as-digit and has suffered a cosmic ray flip in one move list bit, from 0100 to 0110. I guess the latter is more plausible.

In any event, if you'd rolled a six on that post-goal kickoff, you'd have scored a goal.

Known issue, alas. On goals, and the shot after goals, the die roll is frequently misremembered. There are several other instances in that game.

It seems corrupted right at the core, looking at the PGN:
