Hi

The custom currency works very well for buying but for selling it does not want
For the customer it takes into account the research paper with a skin
But for the sale it gives the item of base research paper like currency

Ty

Can you give me an example config item so i can understand it better. 

mousse prob has a plugin that has the paper with a skin

- buying from shop it sees the itemid (no check for skinid)
- selling to shop it gives default itemid without the custom skinid

Hmm, what plugin is that? lol, why is this marked as solved? I could have probably done a patch

Hi I used the plugin https://umod.org/plugins/general-item-modifier
