Summary
A minor update to the game's resolution settings:
Resolutions your monitor does not support are no longer shown in the list - Previously the game would silently default to a supported resolution without telling you which one.
Custom resolutions are now clamped to your monitor's maximum width and height, preventing the game window from extending outside your screen.
This does mean it is currently not possible to span the game across multiple monitors — without clamping you could see far beyond what a single monitor shows, which isn't great without a fog of war system in place.
This restriction will be lifted in a future update once fog of war is implemented.
