Character's head fails to render in thumnail

[RexyRonin]

I just downloaded makehuman version 1.3.0 and while I was casually making a new character, I noticed that in the thumbnail that is created in the 'load' tab, my character's head is missing. I noticed that it's only the head mesh that turns invisible when thumnailing, the rest of the body renders just fine.

I also noticed a few related bugs related to how the program renders your character

• Screen turns permanently black if you save your character while having a custom background activated in the background settings. Either that, or it creates a permanent shadow clone of your character.
• Screen turns permanently black if you make a new in-program render
• Some hairs appear to be strangely transparent. In previous versions this issue only appears when I exported my characters in Blender, but now it appears here too.

Overall, 1.3.0 has incredibly unstable rendering. Can anyone help?
