Torch Stand in wrong state
I'm running 0.7.158B755. I've built a number of torch stands around my area, and have turned them all on. When I leave the area or load a save game, some of the torch stands do no provide light (ie. UI is in the off state), but the background model has it clearly in the on state as the text on the torch stand says "Press F to douse Torch Stand" as seen in the attached screenshot. I have not seen a pattern of why some are correct and others are not, but it's consistently roughly 50% are correct and 50% not. Possibly a race condition when loading the model and UI when moving into a new area.
Hope this helps.
