Amazing mod, probably my favorite one, but theres a few issues I experience. The first one is that some firefighter volunteers disappear after returning to the station, and after a while I'm getting told no volunteers are available. The second issue is that a lot of the forest fires spawn on the border of the map, making it extremely annoying to fight them. Apart from this, the mod is really fun and enjoyable.
Also, I'm pretty sure the interior attack feature is broken (at least for me) because even after being told I have to vent the roof, neither the ladder truck or two firefighters with a ladder are able to put the ladder on the roof.
