This mod seems to not play well with the Permaday mod. I didn’t have a problem for a long time, because I hadn’t created any lights, but as soon as I built a couple of lights, I started getting crash-to-desktop issues regarding an array index out of bounds exception. Uninstalling this mod fixed the issues. Removing the lamps did not - I kept getting the same exception, only with an array length of 0.
Telling the permaday mod to let time proceed as normally seemed to help some, but my power grid and then the game immediately crashed the instant the sun went down and the lights came on. This may have been because by default the permaday mod sets the night duration to zero even when time progresses normally, so it instantly went from sundown to sunup.
