Milestones not showing in the correct order

There is a bug with milestones not showing the correct timeline of events. Using mine as an example: https://retroachievements.org/user/SlashTangent/progress It shows that my first beaten game was Halo 2600 on Jan 6 2021 however, I have games beaten before then. In this instance, I think my first beaten game is Pokemon TCG (GBC) on November 13th, 2020.

@slashtangent I believe the issue here is once a beaten award "graduates" to a mastery, the milestones section no longer recognizes the game as being beaten. Maybe we should change it so it's no longer doing this - it seems the current behavior is unexpected.

Taking a look at the linked page, it looks like it's displayed in the correct order as per your above comment:

Has this been resolved by some other change since this was reported? Or am I misreading this?

[wescopeland]

No changes since the issue was reported.

These are the milestones:

Right now they're also following the award "graduation" behavior that the main content on the page follows. Perhaps it shouldn't?

A better description of the current (and probably undesirable) behavior:

• Let's say I beat a game in January 2019. It's my first beaten game.
• I take a break from RA. I return in 2022 and beat several more games.
• Next, I master the game that I first beat in January 2019.
• That first beaten game no longer appears as my first beat. It's now my first mastery. My first beat is the 2nd game I beat when I returned in 2022.

Wherever this ends up, I vaguely remember that Milestones doesn't have great test coverage (this is my fault). We should beef up that coverage as part of this.

Per #2432, I plan on tackling this once milestones is extracted into its own service.
