What issue are you seeing?

Issue observed: After completing the latest user request, the assistant resumed or reprocessed an older user prompt from conversation history as if it were new. This caused duplicate work and ignored the expected turn order.

Pattern: User sends prompt 1, assistant completes 1. User sends prompt 2, assistant completes 2. Repeat all the way to prompt 58 or 112 or whatever cause its totally random. Then assistant unexpectedly "receives" and acts on old prompt 7 or 35 or something else from the past again.

Impact: Wastes time and token, causes user frustration, and risks making stale code changes unrelated to the newest instruction.

What steps can reproduce the bug?

As mentioned in the previous box, its random, I have had it happen 2 times within an hour and then other times there are several hours between occurrences. There isn't anything that jumps out at me that says x and y keywords in the prompt trigger it or anything.

What is the expected behavior?

Does not pull prompt from the past and reprocess it.
