Upgrading to TE v18.
Since Minecraft 1.13, Mojang changed its internal enchantment system. In order to move smoothly migrate from a pre-v18 TokenEnchant to a post-v18 TokenEnchant on your pre-1.13 Minecraft server, you should capture all your registered enchantments information, so that that enchantment information can be re-used with v18 TokenEnchant.
[b]Step 1:[/b]
Say, you're running Minecraft 1.8.8 server and have been running pre-v18 TokenEnchant.
What you need to do for the first step is to install [url=https://polymart.org/resource/enchantmentlisting.349]EnchantmentListing[/url] plugin and restart your 1.8.8 server with old (pre v18) TokenEnchant.
This will generate "enchantIDs.yml" in your TokenEnchant folder. This file lists all your currently installed enchantments.
[b]Step 2:[/b]
Keep "enchantIDs.yml" in your TokenEnchant folder, and replace your old TokenEnchant's jar file with TokenEnchant-18.x.x.jar. Then restart your server. Your server with TokenEnchant v18 will maintain the enchantment ID information from your old system.
