Bugfix, finally. Took longer than I hoped, but there were some pretty major things going on. Fortunately, I've been able to resolve them at least to the point that the game will function. Specifically:

-Yet another workaround attempt for the width of null error. Hopefully this one finally works.
-Fixed some stuff with the recruitment system so that people shouldn't randomly disappear after being recruited. I still have no idea what was happening there but I made some changes and the problem doesn't seem to be occurring anymore so here's hoping it sticks.
-For now, changed the settings on the save system to just not show character graphics in order to prevent crashing. It's not an ideal solution, but the thing I'd really want to do is beyond my current javascript capabilities. It's on the list of things to improve, but no estimates on when it will happen. It should at least not crash now though, which is the most important part.
-Deleted a few assorted phantom maid's robes that were stuck on a few different characters.
-Fixed the default imp class to be Imp instead of (blank space).
-Fixed the class graphics for the plant minion if recruited.
-A couple of minor graphics touch-ups.
