Conflicting with ItemRetriever

Hello, I contacted you on Discord on April 3, but since I haven’t received a response, I’m also submitting a support ticket.

This plugin is conflicting with plugins that use the ItemRetriever plugin from Umod. 
Could you please add a feature to block ItemRetriever so that this plugin doesn’t use it?

Something like “Block ItemRetrieverAPI: true/false.”

Specifically, when the SuperCrafter plugin (which uses ItemRetriever) and the Shop-UI plugin are both present on the server, it becomes possible to sell items infinitely.
This is because the item deduction process performed at the shop cannot be executed correctly.

I apologize for making such a self-serving request, but I would appreciate it if you could consider this. Thank you for this wonderful plugin.
