Hello!
I’m trying to create a Rust istance with Greenlan template as it’s more friendly over mods with Carbon. I have a istance already running on another server which is fine but i wanted to create another one. but when i run the update it throws this

I noticed that only Greenlan template does that while CubeCoders template still runs fine. I’m trying to remove at least the betabranch string but i’m looking everywhere and can’t find solution :frowning:

Reproduction Steps

  • Create Rust istance with Greenlan Template
  • Run first installation / update
  • Update fails with Code 3
