UX
Improved the notification pin informing about lack of schools - it shows when capacity is about to run out and not only for basic schools, but higher education too.
Resource production tooltip in mines shows estimated time to deposit depletion.
Services, stores and clinics show a local notification when they're getting overloaded by demand.
Palm oil is no longer counted towards food reserves in status bar if its consumption is not allowed by law.

Technical
Adjusted contrast and saturation during night scenes to make them look more night-like.

Balance
Ores can be stored in silos.

Fixes
Crash when the game attempts to autosave if there's an empty folder named autosave in the save directory.
Random crash related to model rendering. Hotfix. Exact cause was not found.
Colonists could enter buildings through unfinished units, then complain about lack of life support.
If a central structure with units was demolished before the units, the units were deleted with it, losing all their resources. The central structure now waits before it's deleted.
Tools that switched overlays (like survey or landscaping) didn't switch back to their overlay if another overlay was activated and deactivated during their use.
Some saved enabled overlays that were re-enabled when the game was loaded didn't properly activate their own toggles.
Exploration could've been queued beyond the edge of the map.
