Hello, I was following the tutorial to make an elevator from the Portal 2 mapping wiki and when I was going to compile the map it said: "Could not open instance file: instances/turbine_elevator/arrival_elevator_a4_base.vmf" How can I fix this?

Thanks in Advance

Edit: Thanks to yishbarr I solved my problem. Thank You yishbarr!

Validate your tool cache.

I think that didn't help

Save your map in the sdk_content folder.

Thank You! That worked. Now I have more things to test around with
