I cannot fiund anything int he instructions about loot groups; nor is the web tool that have a link for active; and finally the hosted page for loot groups is NOT available as far as I can tell...

Is the setting "Loot Profiles" used for loot groups???

I need to know how to use it because I need to make my loot similar to vanilla

Is it possible my loottable.jsopn is not covering all the prefabs?  It has only two heavy scientist prefabs and when I edit the loottable it does not change the loot of the heavy scientist at the bradley / oil rig.

I clearly do not have betterloot set up right.
