You're cool <3

Took a quick look and confirmed the issue, issue source located (a stray comma) and sorted out, the packs should be functioning as intended now.

I'll take a look into it

I installed all 4 packs at once. Whether one I've run into a problem or not, they don't show up in the world. Moreover, other packs stop working.
Started a new game. Everything is as it should be.
I don't deny that I am the only one with the problem. I'm a little dumb. But it doesn't hurt to report a possible problem, right?
