Plugin caused duplication glitch: Using both NoLagg and ShowcaseStandalone at once, can be a dangerous thing to do. Here's why: If two showcases of the same item is too close to each other, NoLagg will try to stack these, to cause less lag. However, this opens up for a duplication glitch. Usually ShowcaseStandalone prevents people from picking up the items, but when NoLagg is added, these items that are showcased will get stacked on one of the showcase areas. The one with no items will keep trying to add an item to it, which will be moved automatically to the area where it stacks. When there is more than one item, a player can toss a diamond to a diamond stack, and the protected diamonds will lose their protection. Therefore, a player can just pick these up, and walk away. This might also be possible if the player just tosses an item of the same kind as the showcase, to a single showcase.
