Too many times players backpack loot while fighting a player. There should be an option that makes it so you can only use backpack when not in combat. Might need to be added to NoEscape instead but thought i'd post the idea.

NoEscape already has built-in compatibility for Backpacks.

Permissions from NoEscape documentation:

• noescape.combat.backpackblock
• noescape.raid.backpackblock
