What's Wrong?

While using Fable 5 with Claude Code, I noticed a recurring issue where team agents would send a reply, but the main agent would immediately ask them what happened to their response and request that they send it again.

Sample message from team lead:
<teammate-message teammate_id="team-lead" summary="Requesting your exploration report status"> Are you done with the ai-chat UI mapping? Please send your full structured report now (or whatever you have so far). </teammate-message>

Response:
“My full report was already sent — it may have crossed with your message. Re-sending it now to be safe.”

This has been happening relatively often. When I ask the main agent what happened, it replies that it never received the message in the first place.

What Should Happen?

The whole point of team orchestration is for the team lead to communicate with it's team, BOTH ways.
