Fixes
- Fixed logic that counts backpacks when too many backpacks nerf is switched on to count unique backpacks so that backpack exposed in two different equipment slots doesn't get double counted (like it did when in accessories slot and at the same time Accessories Compatibility Layer mod was present which exposed it as backpack in curios slot as well)
Features
- Added logic that prevents adding duplicate discs to advanced jukebox in backpacks that spawn on mobs
