Friend has key. I just moved to Alakol now they can't garden with me . could in my old place. She can harvest trees, piggies etc, but no gardening. Bug???
Did you re-issue the key after you moved? When you move, all keys you had issued are revoked, and you have to issue keys to the new place. But if you did that, then it sounds like a bug.
Have your friend "return" your key(s). Not sure if it's possible but maybe they still have the old house key as well? Then give them the new house again.
Dreamer, could your friend please submit a bug report (clicking the bug icon in the game) when this happens at your garden and give a description in the report? I tried to do it now and there was no problem with it, so her report on what happened would be useful. (And, we'll see who it is from the report too.)
(BlackWolf- the old keys get taken away when the player who generated them sells a house.)
