Well.
I accidentally opened steam.
Because i'm an idiot and it's very late.
It started at my activity account-y page, everything there is mine i think and all the friends are mine i think and it looks okay probably.
I then proceeded to close steam again.
I think everything's fine and fixed.
Probably.
I feel it's worth noting that i set my steam account to appear offline.
It's not actually offline mode, but anyone looking at my friends list would see me as offline.
