Sorry again for the trouble, but thanks to your project i was able to root out more than one issue, and I realized I forgot to tell in the documentation, item type, tier name, and table name have to surrounded in quotes when used in script call, updated documentation will relay this!
And the reason it quit working completely is because the minimum level on a loot table was set to 0, I correctly limited it to level 1.
I gone over it multiple times for an hour, testing every command/ script call, and transfering maps, reloading saves, and it appears to be working fine now in the latest version V1.07.
Here's the fixed project, i changed comments and commands to show the script calls that require quotes and where the quotations are required.

As usual, do tell me if anything else gives you trouble!
