Oldchat fixes (#12009)

* various fixes

* whoops

* oops

* oop

* removes that call from escape button on unload instead of adding another one

also just moves escape window stuff into the state entered call, as only one is instantiated whenever the state is loaded (and is not dependent on the current screen)
