While I was playing, I received a message saying that I logged in on another device.  I did not.  I signed back in and it happened again.  But the time I could reset my password, some manged to use almost all of my shards.  I have no idea what the point was, but know I have almost no shards and a lot of rare champions.  Really, what did that person have to gain from doing this to me???  And is there any way to fix this?
