With the new Update you can block the Villagers from movin in randomly.
They won't put their houses on the paths anymore, so that's a great & easy way to place them good!
Ahah, I hear that problem often with the thumb stick.
I don't have Super Smash Bros (yet), so I never got that problem.
For me it was once just like that dying, then my cat made it fall perfectly into the
waterbowl of them (she pushed it all the way over the 3m long kitchencounter to do that q.q),
then someone sat on it (that was funny, but painful to watch xD), once display broke and
while repairing it the whole DS broke and the last one I wanted to change the housing,
since mine was quite used.. well, thanks to cheap chinese quality a sharp piece cut through almost every single cable
and RIP
