What duration for one time patron?

#10 If I'm not entirely mistaken green wings mean that the patron is online, while yellow ones mean that they are offline. Not that your donation is about to expire.

As IM lovlas said.

Thanks.

But I think I saw my own patron wing fade during its last days. How can I see it if when I'm offline?!

But maybe my memory plays tricks on me... I only donated 2 or 3 times, and it's been a while since then...
