Multiple Checkmate bug

for some reason on the notation 3 different moves were mate during the game which were played?

If you go to "View on lichess"

It was atomic.

Not what I mean

Go to view on lichess
Multiple moves where played after Qxd2 but all have an # indicating mate

1. Thats not how atomic works, lichess? 2. It was 3 years ago, lichess might’ve patched it alredy

How does this happen? Game should have ended after Qxd2#

Probably fixed, at least on an analysis board the game ends correctly after Qxd2.

It seems related to this issue, also from 2021: github.com/lichess-org/lila/issues/9541

The issue is marked as completed, though it's not mentioned how it was fixed.
