I am having a few issues with spawned missions.
1) Seasonal missions are spawning including Easter, Halloween, and St. Patrick's day.
2) Police Missions are being spawned by Fire Stations (that are not complexes) and the Requirements page is indicating the Fire Station is a Police Station.
3) A couple of other players have reported mission spawning well above their current build.
Besides just being weird, the missions can't be completed.
