Hi, this should have been fixed a couple of updates ago, but will still break if using an old save. Are you using a new save? Otherwise, where does this start happening for you?
This was really hard to replicate, but I discovered it mostly seemed to happen if you had closed and re-opened the game at a later stage. I’ve played around with how the variables are initialised at game launch, and have hopefully fixed this (without creating too many more bugs). Give the new version a go.
