Thank you to everyone for reporting the crashes and bugs!

[h3]Changelog[/h3]

• Hammer spell and Sickle spell will no longer crash the game when bought (old save files caused that).
  
• Fixed wonky rotation of the cannon when you'd cross a boundary.
  
• Various crash fixes relating to explosions (zealots, grenade arrows etc.)
  
• Crash that happened when a bat hit a grappling hook and it tried to clone it using the cloning collision mod.
