The loot tables in this plugin are absolute garbage.

I just ran a bunch of tests with the default configuration, a custom configuration with rarity overrides, etc. and this is what I got across ~240 military crates. Not everything is listed, but I care much more about comps than I do hazmat suits or search lights.

I was totally starved for scrap in my testing, totally starved for components, and completely overrun with electrical items and water purifiers. There's no way this plugin is worth trying to configure, right?

You should try this BetterLoot Editor and make your own.

Been using this since 2015 and its up to you to configure the loot the way you want it , thats why there are configuration files. some people use 3rd party programs that help configure them , i prefer to do it box by box , crate by crate etc so i get it the way i want it.
Just remember that when you are editing data files you do it with the plugin unloaded, save your changes then reload it, i have boldly stated it because people still forget to do it that way and i am not being sarcastic towards you,

The plugin can't even generate the items and counts correctly, did you make a vanilla loottable from scratch?? The plugin is as old a pookins here, it has old code, any many people worked on it. It does not do what the game does anymore. It randomly picks a rarity 0-4 (there is some scoring so obviously 0 is going to get picked more then 4). Then it randomly picks an item out of that rarity list. It's simple and easy, for something that lets you adjust loot in a container. A rewrite would introduce new bugs and problems, and I'm sure it wouldn't work with the current files. omegablue suggested artemdanilkin.ru but lootify.co.uk is 1000x better imo.

Spend money on alphaloot if you want 'highly regarded'. Maybe that's what they want. I think the idea of setting up a server should be instant is the real flawed part here, because it does take 'literal days, weeks, or months'.

it took me roughly 3.5 hours to (select all)  copy (paste to "new text document" , edit and copy/paste it back to data folder, maybe because it is like me (old and crumbling round the edges) but works fine for me. i have used it through all its code and dev changes without too much drama.
