fast weapon switch would have nothing to do with it.
i dont even touch the scroll wheel in tf2 so it's not that
Strange. I dunno what could be the problem then. TF2 shouldn't weapons switch you to Minigun or Melee until the Sandvich has been consumed.

im guessing since when i eat the sandvich it changes it from 1 to 0 and it thinks its done or something
 
I am guessing it is a hotkey / script problem. Since i have not heard or seen this problem anywhere else.

I don't have this problem and i have no scripts, special huds, or changed keys. So look around your scripts for something.

but in all honestly i don;t know.
