Hot Reloading not working on a single component but works for others

[adammenges]

So I've got a pretty simple project (In case anyone's curious: https://github.com/adammenges/adammengesWebsite).

In App.js I've got the following router, as far as I can tell the router has nothing to do with the issue I'm seeing, but for completeness:

      <Switch>
        <Route exact path="/">
          {homePage}
        </Route>
       {...}
      </Switch>

I can swap out the homePage var for two different components. I literally copy and pasted one from the other so there's nearly identical, aside from the name and file, of course.

One, <Header />, works fine and hot recording works. When I switch it to <Portfolio />hot reloading breaks. It's wild to me, I can't for the life of me figure out what's different between the two and why hot reloading works in one situation and not the other.

Thanks in advance folks!
