Muse's invisible-messages bug: tool-call progress never renders, Meta silent for 36 hours

inductionheads · x · 2026-10-24

inductionheads reproduces Muse's "invisible messages" bug: for any task requiring tool calls, Muse sends progress updates between calls (they exist in the transcript) but they never render on iOS or web — users only see the final reply, so chunks of every conversation go missing. The report has been up 36 hours with 250 likes and 40k views, and no one from Meta has reached out; multiple users confirm it's genuinely broken.
