I am encountering an issue with the Itemsadder plugin for Minecraft. Specifically, the plugin works correctly on the first start, but stops working after the server is restarted. I have attached the error log for your reference: https://pastebin.com/Q3V1SRmE I have already tried updating all of my plugins and disabling them temporarily, but the issue persists. I suspect that this issue may be related to conflicts with other plugins or incorrect settings in my server configuration. Could you please provide me with detailed instructions on how to troubleshoot and fix the issue? Thank you in advance for your help.
