Separate domain appeared behavior overview?
I was looking through the behavior overview and noticed that some months ago (roughly March) an unrelated (to the site, not unrelated to me) domain appeared in the behavior overview.
Would this be caused if somehow the wrong code was used? IE, the analytics code from the first site was embedded into the second site instead using the code meant for the second site? The domain only appeared for roughly 3 weeks, and it was long enough ago I can't say for sure what was happening there. I just wanted to check if this was something others had seen before.
