LimitDrops 1.05 adds processing for shulker boxes broken by a player in Creative mode. Minecraft will always drop shulker boxes in this case, so there's a configuration item to prevent the drop of the shulker box and its contents. To prevent shulker box Creative mode drops, add the following to your config file:
Otherwise, shulker boxes are no longer emptied because the shulker box drop itself includes the contents.

This version also opts-out of Paper's plugin remapping.
