Summary

2026.04.26, 2026.04.27, 2026.04.29
To be honest I'm not long with openclaw, so haven't seen unaffected version.

2 issues:

1. sometimes message into channel root gets linked to one of earlier threads.
2. sometimes message into thread gets unlinked and arrives into channel root.

This leads to wrong decisions, agent assumes I answer "yes" to something it posted earlier or injects wrong context into thread.

For me looks sort of critical.

Steps to reproduce

don't have exact steps to reproduce, feels spurious, but since 2026.04.29 happens more frequently vs 2026.04.26.

Expected behavior

Messages in web ui (sessions) MUST appear as responses to corresponding threads in slack.

Actual behavior

Sometimes messages from slack appear in sessions which have no linkage to threads where messages actually posted.
