What issue are you seeing?

Frequently after restarting Codex Desktop, several conversations loose a large amount of recent history completely, and for history before the lost part, tool calls and file changes are missing.

This is an example where the conversation is cut off about 1 day's worth of work from where it should be. And between every paragraph visible in the screenshot.

I have a hunch that the "cutoff point" roughly but not exactly aligns with past compaction points.

Interestingly the local log files for each conversation still contain all the turns (I'm able to regain most context by asking Codex in a new conversation to recover information from the log file). So this seems to be a loading/replay issue not a persistence issue.

I would really appreciate if you could look into this as it is a severely productivity-breaking and frustrating bug.

What steps can reproduce the bug?

My guess:

Have a long conversation over multiple compaction steps, then reload the app.
Only happens to some conversations, cause unclear

Example conversation IDs where this happened:

019cdf08-912c-7132-86c7-acc1b960dde9
019c986b-0a68-7bc2-b9b6-4e2a4e2a3fec <- happened here multiple times!
019cfe1e-9bd3-7371-a335-6f1dff7dd62c

Will provide more conversation IDs as follow up comments as this keeps happening.

What is the expected behavior?

Every conversation should resume to the last turn that was made it in under all circumstances.
