Couldn't find other recent topic on lost luggage.
I just had a bag delivered (at 11.30pm) at home in London that I've checked in (and last seen) at LHR T2 more than three months ago.
Itinerary was LHR-ZRH-BEG (with about 2-3 hours connection in ZRH), one bag came through fine, second was lost (until now).
