Very disappointing to see that advancements in increasing the call radius have been reversed. It is one of the single biggest things wrong with this game.
The current call radius settings is laughable on the AU version at least, can't speak for the UK or others. I have 2 different networks of over 30 stations all placed in real life locations and I have little clumps of calls generating around each station.
Several of us on the AU version have been lobbying the devs for a long time to increase call radius so now to see that it's been reduced again because it encroaches on other members territories in alliances is sad. Surely that's a problem for the alliance to deal with not the whole game?
We all agree that the best solution is to make the radius customisable, I ideally for each individual station (so that those near ferry routes don't have calls spawning in the water) and with a minimum protection to eliminate cheating - but given that there is next to no development happening in this game at all then out of the options of keeping it as it is or increasing it I definitely vote increase it!
