Overproduction is marked red.

Update from the maintainer

Fixed in v0.16.3 Nothing was colouring overproduction red: surplus has always been green. What was red were the input dots on a machine built bigger than the plan needs. Those could never be cleared, so red was being used for something that was not wrong. They are now a muted dashed grey, and red is kept for a genuine shortage. If you were seeing something else go red, send a screenshot and I will chase it.
