Fishing Village For Sale

I have looked everywhere and can't seem to find what plugin is causing this. My servers have an exploit where they buy air tanks but they are now set to 30 for the same price of 35 scrap. They are buying tons and recycling them. They are able to get tens of thousands of HQ metal in like 10 minutes. I have removed any plugin that deals with gather, etc. but it stays the same. Any ideas on what wopuld cause this as they are supposed to be 1 for sale. Masks end up being 20 and flippers are 25 per too.

you had a plugin change them you need to find the plugin that changed them and make it change it back.

No, I know, I didn't know if anyone might know a plugin that would change them. Here is a list of my plugins.
