Confirmed, at least in the 7/23 Github build. It just doesn’t go away, even after three or four days.
It makes cooking without a filter mask or something near-impossible.
Oh, and smoke inhalation, even from a single “smoke” tile, can damn near kill you. Been there, done that in WTFCAN’TSEE10FEET smoke when the wind changed during a controlled burn of a prairie. As long as you get out quickly, you’ll be somewhat incapacitated for a few minutes but otherwise fine. That said, I’d say “smoke” and “heavy smoke” should affect your eyes - it stings like hell.
