About Rail Bot Unstick
From Factorio Mod PortalRemoves rail collision restrictions to allow construction bots to build raised rails without support pillars.
Rail Bot Unstick is a lightweight utility mod that allows construction robots to build raised rails on any terrain, even when traditional support pillars are missing. It works by modifying rail collision masks at data stage to ensure that rails can always be placed, allowing full compatibility with raised rail mods and automated blueprinting. Note: If you have construction bots already stuck on blueprint ghosts, delete the blueprint ghosts and replace the blueprint to update the robot logic.
No runtime code — pure data stage patch
100% native construction bot behavior
Lightweight, stable, and performance friendly
