Milestone 1.31 STABLE released!

[Chris]

This is a stability update for the default Steam / GOG / Epic branches that contains all the fixes from the 1.31 versions which have been tested on the Experimental branch.

Changelog:

• Fixed the crash that could occur after a UFO gets stuck on the Geoscape (these are resupply missions for Alien Bases).
• Fixed a crash that could occur when starting air combat if the leader aircraft of a three-plane squadron had been split off and the remaining two planes attempted to start another combat.
• Hopefully fixed the "terrain not disappearing when destroyed" issue properly now. If you continue to encounter it then please let us know!
• Dropship auto-fill button now obeys the Vehicle Capacity rules for the dropship.
• Engineering Screen - the quantity arrows for the projects now update correctly if you add a new project and can no longer afford to add more quantity to existing projects.
• You no longer get a building complete notification for buildings in destroyed bases.
• If playing Iron Man, the game no longer always quits to Main Menu rather than giving you the option to quit to Desktop too.
• The "Captured VIP" item in the base stores is now hidden, as it's a research trigger item (and you still also get the Captured Psyon item).
• Fixed the region highlight outline for Soviet Russia being misaligned in some cases.
• Fixed the newlines in the "Base Destroyed" loss condition text.
• Fixed the game showing incorrect values in the Xenopedia for the MARS and Sentry Gun stats.
• Fixed the Cleaner SMG and Accelerated Rifles being equippable by vehicles.
• It's now possible to shoot through the glass doors in the desert trailer park houses.
• Pillars are now crushable (which means the MARS can move diagonally through fences).
