Hello, unfortunately I now have a new problem but I don’t know why.
It worked a few days ago, but unfortunately I overwrote something in the portal script, now the game always breaks off when entering the portal. It’s annoying that everything was working fine. Could someone give me some advice on this? I thank you in advance.

}
I also added moving grass when colliding the player, maybe there is a problem here.
No error is displayed there.
Thank you i make a video for this.
