Hi!
I have a strange problem here 
I tried to push other repository from github to my bitbucket repository branch, but I incorrectly choose branch and github repository are pushed to my master. I know, this is strange, but actually I wanted two repos in my bitbucket (just in different branches).
Now, I have problem with history. In commits history I see a lot commits from github, when I choose commit, it shows that it is from master, but in master is only my commits.
I don't know to fix this issue. I can't delete these commits, because git can't see they in master.
