V2.8 ItemJoin (Bug Fixes):

Better support for Spigot/CraftBukkit 1.8! ItemJoin is fully backwards compatible for any versions of Minecraft 1.9 or below.

Added:

• Clear on World Changed (Forgot to add is back in v2.7... My bad!)
  
• Better support for lesser versions of Spigot/CraftBukkit. Should no longer see errors in Spigot/CraftBukkit 1.8.
  
• Better PlaceholderAPI checker.
  
• Slot (Int) cap out limit. If you define a slot that is not between 0 or 35 it will send you an error message instead of spam error codes. (Excluding Helmet, Chestplate, Leggings, Boots, and Offhand slots).
  

Fixed:

• Null pointers if world was defined incorrectly. Now sends helper message.
  
• Respawn and world-changed give on modifier not setting offhand and armor correctly.
  
• Items not re-adding if count is not the same as the items.yml (Some of the item was consumed or used).
  
• Error if offhand is defined and you switch to Spigot/CraftBukkit 1.8 it will try to still set offhand (does not exist). Now it wont set it at all.
  
• Offhand non support for lower versions message. (Wont set item).
  
• Issue in config... Pants were set in chestplate slot.. lol.
  
• ItemJoin reload command a bit. Now generates new config files when none exist.
