Hey Anushka, I wanted to bring to your attention a weird thing. I've had this garden since way long ago lol. Last night I put it in my world just for the money tree seeds. I got the seeds, planted them and everything was fine until they matured. After that, everytime I told him to tend garden, he would do every single one of mine, but when he came to the money trees planted from yours, he would cancel everything in his queue and reset himself to right before the tree. I'm not sure if this was an isolated weirdness or if it's because of the gardening glitch that came with SN, but I just wanted to let you know that. Sorry for reviving the thread but I just thought of it again a couple seconds ago when I was thinking about them.
I ended up going into buydebug and replacing the trees, and now he does all of them.
