What's Wrong?

Client-side content filter blocks completely ordinary personal messages. Example blocked message: "He was so active, did exercises until 75, then stopped, but until 90 was still active, then health problems started" — personal story about elderly father.

Request ID: req_011CbAS9Ak3Sj1dwwytvvrR8

This has happened 12+ sessions in a row. Started around v2.1.139, persists after updating to v2.1.143.

What Should Happen?

Personal conversations about family and health should not be blocked by the content filter.
