This mod used to only allow configuring the tree hop limit, but as of the latest release it now has the ability to start random wildfires around the map.
The interval is configurable under "Mod Settings -> Startup". I cannot make it a runtime setting because of how the events are registered.
The wildfires can be disabled under "Mod Settings -> Map". This is a runtime setting and it can be turned off without restarting the server.
These wildfires will be devastating. The default interval is for a single tree to burst into flames every 30 minutes. These could be at the far reaches of unexplored territory, or right in the middle of your base. Plan wisely! Firebreaks become an integral part of fire-fighting.
The map will be pinged for each generated fire. If no trees exist on the map, this mod does nothing.
