After switching to the paid version, I faced the problem that resources such as sulfur. Do not appear with a 100% chance.

I went through all the settings, pulled up 2 loot tables at once.
It doesn't help anyway. Maybe I'm doing something wrong?

{
"shortname": "sulfur",
"name": null,
"amount": 80000,
"skin": 0,
"amountMin": 2000,
"probability": 100.0,
"stacksize": -1
},

probability should be set to 0.0 through 1.0, not 100.0

100% chance does not mean it will spawn 100% of the time. it means that the item, if randomly picked to begin, will then spawn 100% of the time. this is explained in the documentation. the option you are looking for is to put this item in the Base Loot table, and enable the profile option for Always Spawn Base Loot Table
