I recently downloaded a super cool map to make a mod server with my friends and is full of lootable chest, but they are empty so I wanted to request (Or if it exist pls tell me) a plugin that refill all that chests. Thanks.
This might not be exactly what you want, but take a look at the plugin Chest Refill.
I saw this yesterday, but look like you need to create that chests manually, and the map is so big with chest alredy placed. Thanks anyways and if a programmer see this post I hope he/she make a plugin for this kind of things.
