Why was Zeta nerfed?

When I messed up transferring the response generation, it used to disappear if I transferred it twice to the opposite side, but now it stays. + It used to be fine if I transferred it to the opposite side and then deleted it, but now it says 'generating response' and I have to exit and re-enter to delete it. Normally, when I edit, I copy, delete, and then edit the copied content to resend it. But now, after copying, interaction is blocked, so I have to exit, re-enter, delete again, and then type. Is this right? It's annoying to keep exiting and re-entering. So frustrating;;
