More than one mod

Things to know

• Each mod keeps one speed for each kind of station and one quality factor, and the newest call wins. If a second mod sets a value another mod already set, the second mod’s value applies and one warning in the log names both mods.
• A mod that calls again replaces its own value without a warning.
• Clear(modId) removes all of that mod’s changes, and then the earlier mod’s value applies again.
