Lootr Polymer Patch
Lootr is a mod that makes all containers inside structures spawn with per-player loot so that every player can loot structures without having a large perimeter around spawn devoid of loot.
This mod patches Lootr to work completely server-side. That is, vanilla clients can join and use the mod. This mod must be installed alongside Lootr and its dependencies.
Lootr containers render as their vanilla counterparts, with a small block icon. By default, this is a gold block for containers that the viewing player has not opened, and a lodestone for containers they have opened. This is configurable.

This mod also removes Lootr's advancements & stats, leaving only the functionality and making it a great drop-in for SMPs.
Currently, all 26.x versions are supported, likely well into the future. Lower versions are unlikely to gain support unless highly requested.
