it says you're using a very old version of Jade. your server should be on v15.10.1, not v8.6.3

[dim turret]

Yeah I fixed that part. I don’t even know why jade was on

now I’m having a struggle with player data

I uploaded my old world. But when I spawn in I don’t have my pokemon or spawn in my house. It’s like it creates a new character
