Improved: The spectator mode's update logic has been improved a lot. This allows it to be 100% consistent regarding items with e.g. enchantment glow. Prior to this update, items switching between being enchanted and not enchanted (e.g. selection in Block Crush and flashing in Simon Says) would update inconsistently. Sometimes the glow would never change, sometimes it would take a few seconds to change etc. This update fixes this and glowing items and other attributes are now updated seamlessly and immediately.
Improved: The spectator mode inventory will now change its size depending on the size of the game. E.g. games which are only 5 rows big would leave an empty row at the bottom of the spectator inventory. The inventory will now reduce its size to get rid of the empty row. This has been implemented to also support inventories larger than 6 rows which an upcoming game is going to need
Fix - The lore would not get added to the spectator item in the settings.yml if the file wasn't new as well as it being a String and not a String list. This has been fixed. (You will have to manually change this if you already updated)
