Trick or Treat Event Bug?

DomoSapien: I've just been informed that the codes have been fixed. They should be giving the correct missions now - those affected by the issue will receive the correct missions via a mass invoice on our backend that will take place sometime today/tonight.

They may end up getting replaced, but since it was our goof we're hoping to let those affected simply keep access to the missions they already have + receive the correct set of missions moving forward. So they'll be able to double-up.
