Changelog:

• Built against 1.15
  • There is an issue on 1.15 when using PORTAL as a material, for now you can fix it by reopening the gate
• Updated and using 1.13+ api version now (better performance)
• Removed EchoPet support, it seems discontinued
• Still supports lower server versions, at least as far as 1.8
• Added some debug messages
• Some optimizations

Reminder that this plugin is open source: https://github.com/NoChanceSD/AncientGates and pull requests are welcome!
The plugin has very old code(Ancient even ), if you are a developer some issues i could use some help with are: implementing tab completion for commands, getting rid of static abuse, testing on older server versions and bungeecord support.
