Hello!

Although you say in the Bukkit Download site that 1.17 wouldn't be a problem (
Requirements: CraftBukkit, Spigot or PaperMC v1.16 or v1.17),
I'm having following errors in my server console

An update to the newest NBT-API will probably fix it.

Hi @MatsG23,

Yamipa v1.0.4 is not compatible with MC 1.17. Try using v1.1.0-SNAPSHOT (v1.1.0 stable will be released shortly).

Alright!
