I can't seem to find the solution to this problem. I managed to reproduce it on my end but something's off. The error that I'm getting is the following one.

Trying to get property of non-object (View: /Users/driesvints/Sites/laravelio/resources/views/users/profile.blade.php)

in ReplyPresenter.php line 13

I've traced it back to this line: https://github.com/laravelio/laravel.io/blob/master/resources/...

Which will call the ReplyPresenter. But after that the trail runs cold and I can't find out what's going on. I'm sorry to say but I'm not going to invest too much time into this because it seems to happen only for your particularly account atm. I'm going to focus on working on the next version of Lio because all of this code will go away anyway.

If you want, you're always free to send a PR.
