Hello community. Today something very strange happened to me. I am trying to figure this out all day but I have no idea why this happens. The code is completely okay. I have researched over 3 hours, and my code is okay. Anyways. I have 2 inventory click events. First one : You run a command. You click an item. Another inventory pops up. You clicked another item. Something other happened. But the inventory click for the second inventory, which pops up after the first one won't fire. I tried to debug them, I seperated them into 2 inventory events, but it still won't work. Otherwise, If you open the second inventory before the first one, the event will fire normally. Any ideas what may cause it ? I will be able to print out code if needed.
