Issues unresolved[edit]

Vessels appear empty[edit]

This bug only appears in the OS X and Linux versions of the game. The vessels are being filled, but the fluid isn't being displayed.

Multi-monitor issues[edit]

The game works without problems in multi-monitor setups, however overviews, for example which reactors have been fixed in factory, will appear severely taller than the screen height.
