[Bug] Multiple sequential plans in single session fail, plan mode re-entry ignored

Bug Description
I can no longer do multiple plans in succession during one claude code session. I used to be able to enter into plan mode... and then execute a plan, and then enter back into plan mode and have you do something additional (but related) and you would work. you would give me a new plan after asking questions etc and then I could execute... over and over. but now that doesn't work. it's very buggy. if I shift-tab into "plan mode on" it ignore it and just auto accepts things. and if I do /plan and type out what I want, it just shows me the first plan that has already been executed.
