This is always a "fun" topic. *chuckles*
What has been your worst loss or blunder as far as rares go? Did you feed that bunch of dates to your packy during a move? Did you eat that fruitbasket? Did you have everything on display in your home the day lockdowns were put into the game?

For me, it would have to be the two original house placement deeds I bought last year...

For some time now, I've been collecting the old house placement deeds. I managed to buy both a castle and a keep deed early on, but lacked the large tower to complete the "big three" set. I finally found one for sale along with a villa placement deed which I also needed. Paid 1.4 or 1.7 million for the pair, I think.

Was taking them back to my tower after just purchasing them...and lost connection with them in my pack. Logged back in to see "Your deed for a large stone tower has been converted into a house placement tool, the value of the deed is now in your bankbox." They both turned into house placement tools, and the current placement value for each was added to my bank box.

So anymore, the deeds never go into my pack anymore. I lock the doors and drag them on the floor, or I use a packy. *sighs*
