On the topic of summons: I know it's still a work in progress, but I noticed in Alexander and Knights of the Round there were textures that were just black. I'm not sure if this is how it was before or if there just isn't a texture injected there.
Alexander - on the ground after the line gets drawn/explodes
Knights of the Round - One of the knights (4th or 5th I think) has opaque black textures expanding out instead of whatever is supposed to be there.
This could also be because I didn't apply the patch properly, but I don't think it'd hurt to verify.
