This is a urgent update. It fixed a serious bug that I have somehow not noticed since the very first release.

Changelogs:

• Fixed a bug with duplicating item when you put a negative amount in /gift.
• For servers that use a vanish plugin, regular players won't be able to send gifts to vanished players without a special permission - "advancedgift.bypass.vanish"
  • This should work with most vanish plugins, depends on how the vanish mechanics work in these plugins.
• Improved plugin messages slightly.
