Custom items in vending machines are showing as "100% Off" and for 1 scrap, but it actually charges the full price still.   I updated to the latest plugin from today.

Can you provide the section of your data file where this is happening (i.e., which defines which vending machine and what the settings are), so I can try to reproduce the issue.

I think it was because I updated plugin after server started.  Server ended up crashing and restarting and it looks okay now.
