This crash is 100% caused by a conflict or an outdated version of one of your installed mods. The game (Captain of Industry, version 0.8.5) crashes during the UI initialization phase (TransportBuildController). This happens because a specific mod tries to modify conveyors, pipes, pillars, or transport logistics, but passes a null reference (NullReferenceException) that the game engine cannot process. Based on your mod list and the nature of the error (a crash inside the transport construction controller), the primary suspects are:
Pillar Spacing and Height Mod (1.0.1) — This directly modifies how conveyors and pipes are built (their height and spacing). If it is outdated for patch 0.8.5, it will trigger exactly this error.
Industrial Expansion (1.0.4) or the "" series mods (Tweaks, Gameplay++, Storage++) — These change recipes, buildings, or storage logic, which can cause the game to lose references to required game objects.

This error appeared with mods installed. If it still happens with all mods disabled, please open a new report here.
