Yes! There is no way of just "bolding" a typeface.
You just have to design the bold version. You should understand the specific needs
of your own typeface. Turning bold is not just pressing a button, that's why designing type takes so much time.

Thanks for the reply, I knew I would have to make some minor alternations to the font, but not to the extent that it occured.

However, once you understand how the "Bold" and other transformations work, it is possible to design your face with these in mind, to make "bolding" easier.

Certain kinds of typeface are more amenable to "push button" bolding, for instance light, monoline faces.

The promise of "Auto" is rarely kept. As Nick says, you can learn some ways to make bolding automation less destructive but there is no avoiding a sound thorough redraw. Think of "Auto" as a starting point only.

This happens when the outlines are in the wrong direction.
Reverse the contours to counterclockwise (Type 1) direction.
