When a teamspace reached its AI conversation limit, any learner who landed on a conversation tile saw an unavailable panel with no way forward. Because the tile never recorded an evaluation, it stayed permanently incomplete — and so did the lesson and the course it belonged to.
A conversation tile blocked this way now counts as complete for progress purposes, matching how the tile already behaves when the AI provider errors out mid-session. Learners keep moving through the lesson, and authors still see the limit notice so they know to raise it.
