Fixes
- Invisible walls on the artillery mission are gone. Root-caused to an engine movement bug that could freeze you in place against slopes, plus stray collision left in the map data. The slope fix applies to every map in the trilogy.
- The last artillery gun now completes its objective - the mission no longer stalls after the final gun blows.
- Fell out of the map? You get rescued. New all-maps safety net teleports you back to solid ground if the world ever drops you.
- Officer heal-retreat restored - he runs for his medkit again instead of standing in the open.
- Rank-up glow fixed - no more square flash artifact on the mid-game XP bar.
- Artillery-gun collision no longer blocks a wide area around each gun, and known trouble spots are fenced off with physical barriers.
