Hi. I'm very new to Twine so I imagine this is an easy fix. I want to have the background color in my game change based on the time of day, (which is mapped to a variable). When the time of day changes, I use <<addclass "body" "class">> and it works, but the second I move onto a new passage the background goes back to its default color so it looks like the class isn't saved. Is there a way to keep class additions through passage changes. I am using sugarcube by the way.
