I'm using 1.20.1, which I understand you may not be supporting anymore. Just in case, however:

I have an event that gives an item and sends a message upon right clicking a specific block. Every time I click the block, the message and the item both send twice.

In case it's useful to know, the item sent is from a random list of items, and it doesn't always send the same type of item (ie: it randomly chooses twice).

Thank you.

I still support 1.20.1 and also sorry for the slow response. The issue is that this event fires both on server and on client so the message is sent on both sides. I have to think on how to fix that
