What You Asked Claude to Do

I have asked claude to resume a work with subagents of a conversation has been closed after I stopped the agents, and opened a new claude code in another window then /resume to that conversation.

What Claude Actually Did

he said that he can't resume a sub agent that has been closed by the user, this is so fruastrating, as you can see in this image:
