I will be clear and simple, I have been in Discord looking for help although they could not help me at all, I found the errors myself and in the file worth.yml, the names of the items must be in lowercase for the file to read them, perhaps an ignorecase has not been coded to ignore the upper and lower case, also the names give confusion because for example the carbon ore instead of being called "coal_ore" should be put in the file as "coalore" but Essential ignores that value, I do not know why circumstance is put like that in Essentials but for someone who does not understand much assumes that it does not work and does not use that function, it would be nice to detail it in the file itself or use the normal IDs.

On the other hand I have a suggestion and it is that in the language file the function "totalWorthAll" returns the following comment: "Sold all objects for a total value of $5" the price is an example, the problem of this is that with the empty inventory without items to sell tells me that message by chat, and other times tells me another message denying that I have no items to sell, it is like they overlap each other, it is very rare. It would be good to take a look at it in case there is something wrong with that, it is nothing serious.

Greetings.
