Possible to add server option for disabling selling?
not sure if it has been added didn't see it but if possible could it be added
I have noticed that removing an item from the sell shop results in a bug that causes the entire item to vanish from the shop. I will have an update soon to fix this. Thank you for reporting it.
also notice that few items in shop don't exist due the wrong spelling and not the shortname

If you do not wish for the item to be sold simply put -1.0 for now. I noticed a design flaw with some of the old code that will require an overhaul to fix.

Like above I have removed the wolf hat from the buy list. and it responds normally like

If you remove an item from the buy list it will remove it correctly but not the other way around, unfortunately. 

Also, it is auto-generated so if you could point out which items are affected that would be very helpful. 

Maybe could add seperate permission to buy and sell items? I am tryiong to setup shop for my server but on high rate server selling items is well OP. Could do with ability to completely disable selling.
