The Cerys mod uses a rendering created by rendering.draw_light to light the entire surface instead of the engine's day-night cycle. This causes a issue with use_rich_text=true text renderings in which icons such as [item=processing-unit] are unlit and display as black, as observed in the attached save and screenshot.

Switching to the map editor which has 'Always render as day' will cause the icons to light up.

If memory serves, this may have started occurring around the time that map-only renderings became possible.
