Setup: OpenClaw on VPS (Ubuntu), Telegram channel, streamMode: off
What's happening: Messages are frequently being delivered twice to Telegram — sometimes with a delay of 5 to 37 to 50+ minutes between the original and the duplicate, sometimes closer together. Happens across different message types (agent replies, cron job results, etc.).
Expected: Each message delivered exactly once.
Actual: Duplicates appearing regularly — same content, no indication the second is a retry.
