I would like to make an (Unofficial) Announcement!
I spoke with Mod Stevew on the support forums and he said that they will put together a list of anyone who has this error (including anyone who posts here) and they will look into it around Monday.
So if you are missing your Mad Scientist Outfit (and possibly XP Tome), then just sit out the wait and it should be taken care of soon.
+1 for the quality of Jagex support, and thanks for keeping calm, my brethren.
So I did the combat beta training thing, but every time I finished the last one, it wouldn't let me exit the screen, my wife had same problem, and so i thought nothing of it, considering I had all the tutorials legend unlocked, and others had told me they had same issues, now my wife has received her exp, but not I, what gives?
@Alarius If this is true, this is good to hear that they at least have some knowledge of the trouble people are having. I would have preferred to get the xp today but as long as they are working on it I guess thats good. I still have not received the xp tome from Diango.
