[Bug/Graphics] Research screen missing graphics/info

When I recruited a champion who adds research points, and the research screen popped up for the first time, some of the graphics--and the info about research categories--for that screen were missing.  Also, my cursor was a red-glowing crossed swords cursor.  When I exited the screen and came back to it, with the normal cursor, graphics were still missing.  I'm not sure if the graphics were there before, because I didn't look at the research screen until this point.  When I saved the game, exited, and reloaded the save, graphics were still missing.

I'm playing a custom faction, which may have something to do with it.

The image to the right is because I use dual monitors.

EDIT:  I can't seem to save designed units either, so I'm guessing this has more to do with the custom faction than graphics, per se.
