Good idea checking this room as a backup! It's really strange that the MMSE bounties are not showing up in either this room or Bounty Land, yet the Mathematics bounties are showing up in their appropriate chat room.

Let us try what happens if we add a new feed. I tried the tag python: mattermodeling.stackexchange.com/feeds/… https://mattermodeling.stackexchange.com/feeds/tag?tagnames=python&sort=featured

The lasts change to the feeds in this room was on February 14: chat.stackexchange.com/search?room=108277&q=change+feeds

But messages with some posts were still posted after that - so that does not seem related.

Of course, we have discussed (basically when this room started) that if you use a single feed, then some questions are likely to be missing.

But in this room the situation is different - it has feeds for individual tags - in a similar way as Listing Bounties and HNQs and Hot and bountied questions.
