I lost a plot because I leveled up from level 9 to 11 in one move by harvesting my sunflowers. I had countless pop ups and somehow my plot disappeared before I was able to place it. So I think, unused plots should go into the gift box (inventory is limited and not available from the beginning).
GREAT NEWS
biggrin you can fix it
simply go to the shop, pick a crop, and plant it on a spot where you DONT have a placed plot and it will auto place it. I figured this out recently, the game keeps track of how many you have earned so it will auto place a plot if you attempt to plant something on the ground
