Will be fixed in the next build. Keep an eye out for 2014.5.16.1611. (I haven't merged the questions. That's on you once the build goes out.)
The gist of the problem here is that y'all use a weird alphabet that doesn't fit into reasonable column widths once encoded. ;)
That is, we move people's "favorite" votes to the resulting merged question and record where those votes were originally cast in the database for future reference. We used to record the full URL of the original question, including the title, and from now on we'll use the short version that just includes the post's ID.
