(Sorry if my posts are coming up too frequently. I'm just kind of paranoid I guess 
)
My friend just accidentally unplugged my Wii U during a Pikmin 3 multiplayer match. While the system still works, I'm still rather worried. Is it probable that the system has been damaged in some small way? Also, if someone with some expertise could answer, what exactly gets damaged as a result of such actions and why?
Thanks in advance!
