I wasn't sure if this was to be put under Plugin requests since I am not asking for this to be made, instead I am rather asking if anyone knows of an existing plugin to do this. So here is a brief story of what i'm looking for. I have a main world where players grow crops and sell them at this fountain right? So then I have a multiverse portal that takes them to the "Market" in a separate world titled "MVPortals". I want it so that, if they're to go to my market world and place a chest in their shop, they can't store their crops, I wan't them to sell/store only things other than the crops. Hopefully you understand. This seems simple but I wasn't sure how I could shorten the question into a Google search, any searches I did make came up with rubbish. Please help!
