When trying to check if the PlayerInteract event is canceled to make sure my code doesn't run I noticed it seemed it was always canceled when I right click the air with armor. I am not sure why it was doing that so I disabled all plugins but mine and it still canceled when I right click armor in the air to put it on. I check this for my Crazy Enchantment plugin to know when a player puts on armor with a potion effect enchantment so that I can add the effects unless it is canceled. I tested this by using a debug message and it always stopped at 2 when right clicking any item in the air.
