Problem
Theres a bug in codex that when context window is almost full but hasn't been auto-compacted yet, sending a new message makes the model reply to the previous message instead. It's ridiculous. I have to manually run /compact everytime, otherwise it just brain-dead. Fix this plz

Problem
This is happening alot the last 2 days. "The trace shows the Animator switched to Biofuel immediately after its conversation context was condensed. It appears to have mistaken an old request for a new one; I found no evidence that you sent anything just now."

Idea
Next can you make it so my agents stop replying to an old message in the chat rather than most recent one?
