My 7-year-old brother found this earlier today. 
You can plant seeds, trees, or buy decorations/buildings on other peoples’ farms with this ‘glitch’.
All you have to do is go visit a neighbour’s farm. Click the cursor button, and click “Buy Now…Multi Tool” (The Combine Harvester). It brings up the market menu where you can buy anything to give to your neighbour.
It comes up with a message saying ‘Your game is out of sync with the server’ so it probably doesn’t save. Unfortunately.
Comment if it saves for you.

While the bug works, it has a very interesting side effect. You plant at your neighbour farm, but plants gets to your farm. When you plant a tree to the place where you have eg. soyabeans, you get both – soya AND tree
yeah, I noticed that, the extra space is handy
how do i get my farmville out of sync with the server
I dont know what you mean! I cant do it!
