Hi...
I know this bug has been discussed here a few times, but I couldn't solve it despite wiki and posts here. First of all: I understood it so that - when I use citizens-main - I should not use the citizens plugin, really just purely the API. If I misunderstood, that's probably already the error xD
If not, here is my problem: When I try to spawn a NPC at the player's place in a PlayerJoinEvent, I get the error: java.lang.IllegalStateException: no implementation set. I just copied the spawning from the wiki, so there shouldn`t be any error there.
I do indeed have the Maven shape plugin, but I use instead of Maven's builder IntelliJ's. And yes, I export citizens-main and it ends up in the jar file as well.
I hope someone can help me there :D
