Hello.
Recently I migrated my SVN repository to Git. But when I pushed this repository to the new bitbucket repository, half of my commit comments went away. Here how my repository history looks like on my machine:

And here it is on bitbucket:

Apparently it is a site's issue, because now, when I cloned my repo to the local machine, the history is here.
