Small Update:

The logic and process of using Commands inside of Crates is now fixed.
Usage now:

• Put command ACTION in main/root container: runs every crate open.
• Put command ACTION inside a nested container: it is rolled with nested container logic/chance. This will allow you to put a command in as one of the rolled items. If you, for example, put in a diamond and a golden apple and a nested container with a command in a crate, as the three options, and it's a tier one crate, it will no longer run the command every single time you open the crate. It will now run either the diamond if you roll it, the golden apple if you roll it, or the command if you roll it.
• Command-only crate now works when command is at root/main container.

World Guard behavior now works as intended and World Guard should not block players interacting with corpses if they have the permission to interact with corpses for region flags: build, place, or place blocks, or break blocks.

Other boring background bug fixes and performance upgrades that you will not care about.
