I placed 44 Ore/Gem carts (total), 40 "10th anniversary "stumps" in my home. I had to re-position over 1/2 of them, so I chopped them to redeed them. I sorted them according to which type of Deed it was (cart or stump) then moved to another part of my house (a different plot) & went to use them again, and they were gone.
I first thought they were "dupe" items (they were a gift from someone, & it was standard for items to go "poof" upon redeeding long ago....But, they normally dont redeed, or stay in your bag long enough to be moved (I sorted them according to cart or stump) & stay for 30+ seconds.
Im afraid I lost 20 ore/gem carts & 20 stump deeds to my house/toons "sever crash bugginess. I doubt Ill get the deeds back, but Im placing the info here to aid in other possible prblems for others.
