Just encountered a bug: I had four series and bought another; then went to the archive, put an old one into the left folder (in order to sell it) and the other one into the archive; then went back to the movie agency, but both series (the old and the new one) showed up. I sold the old one and went back to the archive in order to check what would show up there: now I’ve got the new series twice, once in the archive and once in the left folder.

Just got rid of it: went back to the archive and clicked in the series in the left folder once again – then it went into the right folder (now there were five entries in my archive). After leaving and re-entering, everything went back to normal.

=> no fatal bug, but still unexpected behaviour ;)
