I didn't make any changes to Rosie in this release and I couldn't reproduce the issue, but it might still be a real problem.

If it happens again, make sure you note down exactly what she was/wasn't wearing when it happened, and who else was in the game, and if you ran it from the command line, any error output that may have come out from it.

In my experience black screens usually mean the game ran out of memory and couldn't load any new images.  When that happens just save, then kill and restart the game.  If it keeps happening, try launching from the command line with this, which should give it a bit of extra memory (assuming your computer can handle it, but 1.2gigs isn't that much these days)     java -Xmx1200m -jar csp.jar
