Does this error happen every time? If thats the case please add the line

#define DEBUG

at the very top of the plugin file and send me the produced output.

With your current error message it is not possible for me to reproduce your error.

I would also recommend you to make a backup of the file oxide/data/Loottable/custom_items_v2.json and then delete it. If that solves your problem your custom items file was not formatted correctly

ok ok so add the #define Debug where in the top of the cs file or in the config file? and i can try again today with i will also look into the lootable custon item folder and see if there in there as well and if not i will see what i can do about reproducing this i was trying to make paper look like a roll of tp i have the skin id number and everything never had an issue like this before with this plugin 

ok so wierd my custom file still has the loot i created but its not showing up in the ui?

The define debug should be added on top of the cs file, not the config. Could you also send me your custom items file so I can try to reproduce your issue

yes this section is only suppose to be the last one not the top one tried removing it and it came back
