Just did a bit more testing and it appears to be the event. Even after removing the code to change the bool, I put in print("test) and that didn’t work either. The value is also inside a tool which is inside the backpack
Alright, then if you are still having problems with the code, one thing you can consider is looking into how the event is being called / fired. Here is a good link where you can see how to properly receive and fire events from servers / clients. I use this resource a lot!
