Due to a recent change to the Edit Profile page for all forums you can now navigate between every tab on that page without your browser having to load a new page. This means that the route name that the plugin relies on to pick out the Personal tab is no longer there to be referenced and thus the plugin has no idea to show the field when opening the Personal tab from a different tab.
If you visit the Personal tab directly via its URL or refresh the page the field shows, but it won't show under any other circumstance until the plugin is updated to check against the proper route name.
For those of you having issues editing the relationship status; This is how you solve it.
Remember to check out the open threads and the plotters for new plots and threadage!
