What issue are you seeing?

Yesterday, while using a normal Codex chat, I encountered a bug where, after several exchanges and making significant progress on a project, the conversation suddenly reverted to an earlier point, and all the work done after that point disappeared. I eventually created a new chat to see if that would fix the issue, and the bug seemed to be gone.

However, this morning, when I tried to continue working on my KRS project in a Codex Work chat, I noticed that ALL the work I had done yesterday had disappeared, and the conversation had reverted to the state it was in two days ago.

So not only have I lost all the work I did yesterday, but the token usage from that work has still been counted and has not been restored.

This is unacceptable. I have lost hours of work because of this.

What steps can reproduce the bug?

What is the expected behavior?

I should have found my project exactly where I left it the day before, instead of being taken back to a conversation state from two days earlier.

Investigate the conversation state rollback affecting normal and Work chats; done means conversations reopen at their latest saved state without losing work or incorrectly counting tokens.
