There have been some sleeptime agents created during a short window where the agent has stopped receiving messages from the primary agent. We have fixed this issue, but it requires that you re-trigger sleeptime for the primary agent.

This is easy to do:

```bash
curl "https://api.letta.com/v1/agents/$AGENT_ID" \
        -X PATCH \
        -H 'Content-Type: application/json' \
        -H "Authorization: Bearer $LETTA_API_KEY" \
        -d '{"enable_sleeptime": true}'

```

Let us know if you observe any further issues with sleeptime agents.
