New Scripts do not load. Old scripts load fine.

The title explains it
I try to make new script and it does not load and shows as not running while trying to load.
If I open old script it loads easy.
Sometimes it is the other way around.
Why does this always happen?
Now we pray scripts upload and do not corrupt after small changes?
This gets very old please fix it.

Everything works bad since the new viewer has been released, I don't know what are they doing to the grid.
