Yeah, I think when I’m indoors the smoke’s getting obscured, and then however drawing previously-hidden-tiles works is considering it a permanent part of the architecture until a harder map reload (using stairs).
Good to know it’s a graphical change, and not because my guy got so addicted he smoked his pipe that much harder. Also, pipes seem to be giving me the older method of smoking, immediate use, one hit, effects. None of that ‘lit for a while’ business. Downside is I seem to be getting nothing but -50 morale cravings by activating it. It literally only makes things worse in the last few experimentals I’ve had any time to try this week.
Cigarettes/joints, on the otherhand, are working wonderfully. I have a bazillion cig butts that can and will be re-used.
