Just checked and the error does not occur when only the NEW Module & Extension are loaded. So it is possibly to do with teh hew theme. As previously stated, I woudl create all options in the character sheets - been reading
Dark Decade From Dust To Dawn (A Buffy the Vampire Slayer version) and the characters could have both CHI (Vampire Slayer career) and MAG (Sorcerer career) at the same time.
The images are there - though they are not included in the reference as they are represented by "blank space". Clicking the "blank space" opens the image, so they are linked (see attached image). Also the WOIN logo on the Credits tab is also the same.
