Chrome developer tools do not show all JavaScript files any more

Not all JavaScript files are visible in Chorme Developer tools any more.

Google Chrome is up to date. Version 44.0.2403.130 m Debug version of the app. Scripts in the head.

<script src="/Scripts/jquery-ui-1.8.24.js"></script>
<script src="/Scripts/jquery.validate.js"></script>

...

<script src="/Client/Statics/GuiContainers.js"></script>
<script src="/Client/ClientDAL.js"></script>
<script src="/Client/ClientLayoutUpdater.js"></script>
<script src="/Client/ClientRenderer.js"></script>
<script src="/Client/ControllerLocator.js"></script>

First part of the scripts is visible in Chrome Developer Tools under Sources menu on localhost/Scripts/* path. Second part of the scripts is not visible since yesterday. What is the matter with the Developer Tools?

There are no errors in JavaScript console. I can see successful requests for JavaScript files in network tab. All JavaScript is loaded. Application works fine.

What is the matter with the Developer Tools? Does anyone have an idea?

If I add localhost "folder" to the workspace, everything is visible, even server side source files.

Opened the network tab in developer tools and pressed F5 to refresh - thanks @Seano666 for your comment on the question

For me I just had to open the Developer Tools settings and click on the "Restore defaults and reload" button in the first tab.

Then all my local scripts showed up again and debugging was back to normal.

Add the debugger; instruction at any part of your script, the debugger will stop at this point and show you the script, even if the script is dynamically loaded.

                onSuccess: function (result) {
                    debugger;
                    combo.empty();
                    $(result).each(function () {
                        var option;

                        option = document.createElement('option');
                        option.value = this.Id;

                        $(option).appendTo(combo);
                    });
                }

Try right click on reload button in developer tools.
You'll get a menu from which you can choose: Empty Cache & Hard Reload.
That worked for me.

Problem: I had been developing/debugging for some time, and then I encountered a similar issue. Even though my console logs showed line numbers, when I clicked them, I was taken to line 1 of a blank page. My scripts were embedded in the html, so I could see them in the Elements tab, but when I opened the file in the Sources tab, it was just blank.

Solution: The fix for me was to copy the url address and paste it into a new tab and reopen dev tools. The original tab had gotten into a bad state somehow.
