(fix): resolve simulator region handling bugs from refactor

- b475547 caused these bugs
  - guess I never tested the Simulator after the refactor?? could've
    sworn I did....
  - these seem like artifacts maybe from a mixed up rebase/stash or
    something as they're what I wrote before I was sure what the
    regionsInterface would look like :/
