Thank you for your quick reply!
The jam is https://itch.io/jam/boss-rush-jam-2023
I couldn't see it on the https://itch.io/jams tab in the schedule/timeline.
It's... back now? Which is great! But it's lower on the list's order. The jam used to be 8th from the top, and now that it reappeared, it's closer to the 45th. When it disappeared, I used ctrl+f to find "Boss". We weren't on the page despite having been on the webpage for 3 months and starting the jam that day with 900 users. We also had users on our discord that reported the same thing.
I guess it resolved itself somehow because we're back, but it's curious why we disappeared from the list to begin with when we had so many that joined. Would the total jam count on that list have a limited index?
I'm just trying to think of other things that might have happened at this point to help.
We also made an edit to the jam page itself on that day. But even after making the jam edit, we were still on the timeline for a few hours before disappearing.
That's all the details I can think of. I hope this helps!
And! thank you for making itch.io!
