Big thanks to Mime in the comments for pointing out some of these issues and suggesting ways to solve them!

• Most if not all vanilla body locations that were missed in the initial release are now part of the checks for comfort modifiers. If I missed any still, do let me know.
  
• All sandbox options have been reorganized
  
• Scrap Armor support is here! I have no clue how the shields work, afaik they're not considered clothing, so these will have to be revisited when I add equipped weapon support for things in your hands/back/etc.
  
• Pillows now give a comfort bonus! As long as the pillow is placed on the ground and within 1 tile away from the player, it will give you a comfort boost.
  
• correctStats() now checks if ALL players are asleep when deciding if 'Snug as a Bug' comfort level benefits should be given.

- Added an additonal sandbox option to disable 'forceAwakeIfSnug' functionality, almost the exact same as 'forceAwakeIfVeryUncomfy' option.
- Disabling this sandbox option will simply prevent the mod from forcing the player to wake up when their fatigue hits 0, and instead allows PZ to handle when the character decides to wake up.

Update 2 is live bringing sandbox options to Comfy Sleeping! If there are any issues with sandbox options or incorrect option tooltips, please let me know.
If more in depth explanations are needed, check the "Sandbox Options" discussion page!

Bugfixes:

• Snug as a bug: Being at the maximum comfort level was actually making the characters endurance regenerate slower instead of faster.
