I've lost owls to its annoying isn't it... Anyway you can see your old owls by going to quick links. Under miscellaneous there is a thing that says 'owl posts' click that and you will be able to read them but not send any.

If you want to keep sending/receiving owls until there fixed your going to have to open a second account.. Heds, Alo and I have already done that and its ok.. Annoying to have to keep switching though. Sorry this is all I know about it hope this helps...
