In a game I moderate's stats https://www.speedrun.com/pdz/gamestats fullgame works as intended, but none of the ILs seem to. Is this something I've bollocksed in the settings or are other people having this issue too?

What is not correct about the IL stats?

to me the display does not change from the fullgame graph, there's another user who has the same issue with that page so I don't think it's just me

Can confirm that I can't see the graph for IL's, it's forever frozen on the full game graph

I checked the WR graphs on all games I moderate that have ILs. The graph doesn't update when you choose an IL with zero runs, but otherwise it works fine.

Obviously it's not the case in your game, because every level there has runs. I can't see the graph for ILs in your game either.
