TLDR: How do I get a new map-change mod to appear in an existing railroad?
A few railroad days in, I decided that a short run-around track at the sawmill would be good to minimize the shoving of loaded log cars.
So I fired up the editor, added the standard mapData, terainTileSets and mapLayers. Then created a short run-around siding and saved the mod.
I then started the game, selected my new mod in the mods window and started my railroad. I selected “Keep My Current Mods” in the window. Went to the sawmill and my new run-around track did not appear.
In later experiments I created a new railroad and found my mod in the list of available maps along wiht “Railroader Base Map”. I selected my mod as the map, and what do you know, it worked!
Edit: At some point in the tutorial on the new railroad (prior to freight), after a couple of save/reloads the run-around track silently vanished.
So, How do I get my little map change to appear in my existing railroad?
