Vending bug

The plugin seems to randomly allow players to buy from vending machines when they shouldn't be allowed to. I am attaching two screenshots here that show you I can buy an item from a vending machine even though vending is disabled for this tier. It's the only one at Outpost I could buy from. Before this, I restarted the server because I found a different vending machine at Outpost that I could buy from, but after I left that vending machine and returned to it, I couldn't buy anything. In addition to fixing this, maybe add a feature that auto closes the vending UI when a player tries opening it if vending is disabled?

I wiped the server and it all seems to be working now. It appears if you change the Vending setting, you have to wipe the server or else it doesn't work right. I tried multiple vending machines/vendors before wiping and some allowed the selling of items. After wiping the server, I couldn't buy from any vendor anymore.

I spoke too soon. I can buy from vendors again after being on the server for a few minutes.
