What issue are you seeing?

please see attached chat. codex hallucinates/ gets stuck, responding to instructions in PRIOR turns (not the current one) . Clicking edit for the current turn to change the instructions does not get him out of this. This happens quite often , almost every chat at some point after it accumulates a certain number of turns .

note, codex STARTS the turn responding and working on things i asked him to the current turn. it is only when work is completed, that the work portion is collapsed and he begins summarizing, that he jumps back aaddressing a prior turn.

In the chat log, see the last turn and penultimate turns. it is evident that he made a commit -- which i asked him to in penuiltimate turn, followed by new instructions in the last turn -- however both penultimate and last turn he comes back about making the commit.
