0.9.59b New BOSS KV-2-2-2 and Off-map Artillery!

Hey Commanders! This update is absolutely packed — a brand-new Boss, a new mechanic, a new live illustration, and tons of optimizations and fixes! Come take a look~~

• "KV-2-2-2": The latest masterpiece from mechanic Yulia! Equipped with triple-mounted 152 mm guns — terrifying, isn't it?
  It will continuously bombard any enemy within its vision the moment a mission begins!
  
• KV-2-2-2 has been added to the Tournament Database and will appear as the first Boss, randomly alternating with Hermelin.
  Defeating it grants one of its three turrets at random!
  
• For testing purposes, Hermelin has been temporarily removed from the Boss pool. Don't worry — that hot-tempered lady will be back soon!
  

• You can now call in friendly off-map artillery to cover a wide area with overwhelming firepower!
  
• It will fire all remaining "ready racks" at once, then require a long reload time.
  
• Vehicles that gained Artillery Strike as a secondary weapon in this update:
  AS42/47, T17E1
  

• All AI vehicles now take 3 seconds to recover after flipping over (this is tied to a certain Boss mechanic)
  
• Added an optional live illustration for Sunday!
  
  
• Improved the save system and fixed issues where some players could not load their saves
  
• Adjusted armor penetration and armor calculation: high-armor vehicles now perform better against high-penetration weapons
  
• Updated HE mechanics: HE shells now reduce armor using penetration first, then deal explosion damage.
  (White Tiger's HE shells finally got buffed... but is that really good news?)
  
• Improved the battle UI's direction indicator, now much easier to spot and navigate
  
• The Lemon UI can now display six digits (you shouldn't be able to exceed that... right?)
  
• The skill "It just work!" no longer affects Boss turrets
  
• Fixed visual issues with Zimmerit on low graphics settings
  
• Removed some Czech hedgehogs from the Shoreline map
  
• Fixed an issue where enemies would freeze after defeating Karl
