Changelog, version 25.07.11

UX

• Difficulty settings are saved between game sessions.

Fixes

• Random crash when trying to build any type of stockpile or when loading a colony with stockpiles in it.
• Crash after a Construction office was upgraded to a large one.
• Random crash related to tutorial.
• Setting cargo ship distance difficulty too low could cause infinite loading. Such low settings are no longer allowed.
• When clicking the upgrade button on a Construction office before Large construction office was available, no upgrades were shown. Now the large office is visible, but grayed out.
