[Bug]: Counterfeiting bullets and sight dupes

[zKOSMOSz]

Confirmations

• I am using the latest plugin version with the required dependencies.
• There isn't any open issue that shows my problem

What happened?

It is possible to counterfeit bullets; if you stand at the correct angle and location, you can load arrows instead of bullets. As you change your location, the angle you need to use to load arrows also changes. The damage will be the same as from bullets if you charge the arrow.
You can also dupe weapon scopes.
More details about this can be found in the videos.

You can ignore the enchantment; we enchanted it on purpose. But the firework is a bug.

Does this happen with just QualityArmory and no other plugins? ViaVersion and ViaBackwards also cause bugs in many other plugins and that could be the case here. Try using just QualityArmory and see if the bug still occurs. If it doesn't bug again, it's a plugin compatibility issue which probably won't be fixed. And if the bug still occurs then it is an issue with QA and will be worked on at some point.

Please double check this ^

As @WhatYouTalkinAbout said, that's a very odd bug so I need you to double check if the issue happens without other plugins and with the last QA dev build
