There seems to have been an unannounced change overnight to the way bushfire (wildfire to you non-Australian players!) missions generate.
They used to be only generated by fire stations with the bushfire specialisation built, but now all of the bushfire missions now state:
Generated By: Fire Station or building with Bushfire Specialization
Due to this change I am now finding that bushfire missions are being generated in by CBD areas, well away from any bushfire assets or buildings that have had any bushfire specilisations built. I'm only speaking for myself but don't think many in our alliance will have seen this change yet. Also I will also need to check if players without any bushfire extensions are seeing these missions and re-update this post accordingly.
Are any other Australian players noticing this too?
