Pregame unlock bug from NIPD 2025

[JasonRajtar]

We encountered a bug during NIPD 2025, here is how we hit it:
0. Start with main puzzles have lone prereq of MS-DOS and pregame puzzles have lone prereq of !! Start the Event !!

1. Solve !! Start the Event !! for all teams
2. Notice that all teams have pregame puzzles and MS-DOS unlocked when we only want them to have MS-DOS
3. Go to MS-DOS status page and add the 10 pregame puzzles to the list of puzzles it is the prereq for
4. Go to !! Start the Event !! and remove the 10 pregame puzzles from the list of puzzles it is a prereq for
5. At this point, if you look at the status page for any of the pregame puzzles, they all say unlocked for everyone
6. However, if you look at the state map, the pregame puzzles show up as yellow (locked) for teams that have not solved MS-DOS yet

We're not sure if there is a bug at the moment, but here are the concerns:

• The pregame puzzles weren't showing up for those teams - we weren't able to verify this as we didn't have a team in this state.
• The state map was lying and showing puzzles that were unlocked as locked - we definitely saw this, but...
• ...puzzle states often don't update until a member of that team goes to the puzzle page and refreshes the page. It's possible those teams just hadn't gone to their puzzle page and reloaded it yet and maybe this whole issue isn't an issue at all. We would need to test this to find out.
