I thought this might be a known problem, but I don't see it mentioned. When you create an internal link (i.e., to an existing flightsim.to page) from a new upload page, the URL is broken when you go to click on it after publishing. This results in your having to go and edit the link after it has been published, which is getting frustrating.
If left unedited, the URL omits the "http://" and instead inserts a couple of dots, rendering the link broken.
