Помогите Помогите с WorldEdit на SPIGOT 1.16.4

Главное что хотели сделать это перенос с 1.15.2 на 1.16.4
Перенесли, хотим отрегенить заново чанки на которых ничего не задействовано
Но при команде //regen выдает ошибку и отправляет в консоль
Вот что в консоли пишет

[00:19:20] [Server thread/INFO]: Lexa_Fun issued server command: //regen
> [00:19:20] [Server thread/WARN]: Regeneration via adapter failed.
java.lang.UnsupportedOperationException: Missing BukkitImplAdapater for this version.
