Metatrader 5 mql editor idiots. I have made changes, saved file and it is empty. I can only undo changes, which makes it become as it was before changes. Fucking idiots.

Later I see when I open the file from windows browser in notepad++ - tthe changes exists. What a fuck bullshit. So at least they exists but idiots show same file in metaeditor with old changes after undo or empty if not undo.
