2.0.3 Changelog

• Updated version number.
• Changed Models for all backpacks to change how the backpack handle is displayed.
• Three dummy backpacks were added as a workaround for a UI issue, and a new Null backpack was added for Create Mod compatibility.
  • UI Issue Explanation: To explain, the Backpacked menu cuts off the first three backpacks when I added the WoC backpacks. To fix this, I added three dummy backpacks to fill this space.
  • Create Mod Compatibility: When the Create mod is installed, the Backpacked mod adds another backpack, which causes the first one to be cut off. So, to fix this, I added another backpack with a stylish null texture.
  • Important Note: Sadly, you can't have the null backpack with Create installed. I did some testing afterward, and you can have the null and the Create backpack together. I have a few theories about why this happened, but I will keep the null backpack instead of fixing it, because it's a cool feature (and I spent too long on the texture for it not to be in the game). I might even make it a feature.
