Updating is optional. This only fixes an issue that appear on servers that has ArtMap presented. If ArtMap's force-artkit option is enabled, it causes any gifts the player received while painting to disappear when the player dismount from the easel, and creates an exploit where the players are able to give the artkit to the others.
Changelogs:
Fixed an ArtMap issue
If ArtMap's force-artkit option is enabled, AdvancedGift will check if the player is working on an artmap, and prevent them from sending or receiving gifts.
"/gift help" now fetches the command usage instead of saying "help" is not online.
Improved some plugin messages
Added a bit more usage info when using "/gift" and "/gift help"
The plugin is now less rude when the player tried to use /gift with nothing in main hand.
