Starting today, my vehicles when dispatched to a call will sometimes not find a road route to the call and instead drive straight across the map. At first I thought this might have something to do with some vehicles response time not calculating but that appears to not be the case. When the vehicles drive straight across the map it also shortens the response time by about 2-3 minutes.
Here is a screenshot with an example.
This obviously doesn't happen in all cases but happens enough to be an issue when playing.
I have noticed this issue when using the app as well as when playing on my Mac using Safari and my desktop in Chrome and Firefox.
