Tweaks
Mod category: Tweaks
Small changes concerning balance, gameplay, or graphics.
What I did:
1. Installed RSO.
2. Generate a new Railway map without changing any settings.
3. Moved a save to the server.
4. Added RSO mod to the server.
After joining, I see a map without RSO generation, but in single, it works.
