I participated in a game jam that has ended, but the scores aren’t showing up on the scheduled date—they aren’t showing up at all. I know this is a recurring bug, but do you know of a way to fix it? I’ve contacted Itch.io support to report the issue, but I don’t know how long it will take them to respond. I hope there’s another way to fix the problem…

The game Jam : /jam/gaetans-game-jam-07

Ticket ID : 400700

what known bug? i personally havent seen that (from both host and participant sides) and expect the host hasn't made the results visible yet, for whatever reason. 

the jam has a discord server; have you tried contacting them there? and, no one has posted anything about it in Community; you might want to wake the host up either way?

meanwhile, if there is a bug, one thing the host can try is, after making sure results are set to Visible, set Vote Ending Date/Time to something else (maybe 10-30 minutes into the future) and Save as effort to re-trigger?

The same has happened to a jam I entered that just ended. /jam/gump-jam-3/results/vibes

The average number of ratings per game was 6.0 and the median was .

The median rating is missing in this text. And below it just says

The results are not available yet, come back later

It matches exactly what's happening to OP's jam.
