I've had reports on my board of the "award details" button in the profiles linking to the memberlist group view page (randomly, and not always). When I looked into it, I couldn't find the source of the error.
Its not because of my custom profile mod (tested this by looking at Gold Marra's and Legends account, Legend is custom with a bg and marra is default with default bg), a user's group (tested this across every usergroup), or a specific medal (tested this) a certain number of medals (tested this) or a certain category of medals (tested this). All of the codes seem to be in working order, but for some reason, I can't find ANY common link between award details that will and won't link to the group mode of the memberlist and the ones that work properly. I'll keep at it and see if I can figure it out.
My board has a testuser account, username:testuser pass: testtest. There is a link in my www.
For reference, these user's profile award details are bugged: Thewizkid, Gold Marra, Twilightstar, Norid, wolf, and probably a lot of others. And some that aren't bugged: lovelyafterthought, xxlexxyxx, YES, Astoria, Legend.
I've tested the medals mod both with and without the custom profile modifications I made (original and modded)--and both are bugged in the same way.
