When I customized my loot file to about a 5x server's config, the loot crates and everything else is working just fine, but some, id say arround 50% of the barrels on the map give default loot. 

I think this is because that is a new barrel type, and your config hasnt been updated in ~5 months. Can you fix this please?
 
Thanks.

Its already fixed, may search other threads here next time...

How to:

Open LootTable.json and add:

"assets/bundled/prefabs/autospawn/resource/loot/loot-barrel-1.prefab": 
"assets/bundled/prefabs/autospawn/resource/loot/loot-barrel-2.prefab": 
"assets/bundled/prefabs/autospawn/resource/loot/trash-pile-1.prefab":

Dont forget all the "{" and "},"

Open BetterLoot.json and add:

"assets/bundled/prefabs/autospawn/resource/loot/loot-barrel-1.prefab",
"assets/bundled/prefabs/autospawn/resource/loot/loot-barrel-2.prefab",
"assets/bundled/prefabs/autospawn/resource/loot/trash-pile-1.prefab",

Thanks, you're a life saver.
