Thats it the problem!

• Server version: 1.14.4
• Client version: Badlion Client 1.14.4
• Plugin version: 2.1.27

Thanks! I will fix it this week, I think it's due to 1.14.4 missing a method I use to detect item used in the projectile event.
I hope to find a way to fix that since it may not be possible.

I suggest you to consider updating to 1.15.2 as 1.14.4 is not that great in terms of performance and stability.

have a nice day!

Thanks this will be fixed in next update
