dispatch centres

i always have my buildings assigned to dispatch centres, i have a dispatch centre per county, so that all my buildings within that county come under that one county's dispatch centre. i just expanded to northern ireland a bit and i'm already getting a hare coursing call there, i only have 3 fire stations and 1 police station in the northern ireland dispatch centre though and my police station there doesnt have a dog unit.

is there a way to fix this with a setting or is it just a bug/glitch?

Select the dispatch centre you’re using for Northern Ireland and edit it (go to the page where you can set a custom logo for the building). In that edit section you can check a box which states “create own coverage area” or something similar. This will cause missions spawning from stations assigned to that dispatch centre to only spawn at the requirement levels satisfied by the number of stations at that one centre.

thanks, do i have to do this with all dispatch centres i have now and ones that i get in the future too?

Only if you want the calls separated by area, if you do this with all centres you could miss out on larger calls

so how do i make it so that i only get calls in that area if i have the required amount of stations?
