Factorio Forums

OS: Linux (Arch rolling)
Demo version: Factorio 0.12.24 (Build 17689, linux64)

I finished playing the tutorial mission in the demo so I wanted to try the pipes and the other mission but upon selecting it it crashes with the error

Error Util.cpp:49: Unknown entity solar-panel (Maybe you loaded alpha save from demo)
Attempt to use different prototype to traverse save of already removed entity called "solar-panel" failed.There is no other prototype of the same type (solar-panel) to be used to load the entity.

Confirmed in Windows demo.

Transport belt madness and Tight spot are included, but not functional.

I don't think they are supposed to be included, as they were not included in the lowest tier previously.

Correct, they are not supposed to be included, this will be fixed with the next version.
