Yet another backpack mod this time with backpack you can place in world, color in different color combinations, upgrade with more inventory and enhance with many functional upgrades
Fixed code that checks for removal of backpack while it is open to also check if the stack count is still 1. There was an interaction with item frame where this could go down to 0 while still keeping all the remaining data allowing for dupes.
Fixed backpack pickup logic to properly check that infinity upgrade before telling player that the "backpack with infinity upgrade can be picked up by admin only". The issue previously caused all backpacks to say that even though they didn't have infinity upgrade.
Fixed Chipped upgrades to be included as optional entries in sophisticatedbackpacks:upgrade tag list (and thus not break loading this list when Chipped isn't present)
Changed the way items are checked for whether they can go into upgrade slots to only use sophisticatedbackpacks:upgrade tag even for the base mod upgrades so that it's consistent with how these are checked when it comes to upgrades from any addon mods
