Thanks, Mark. Your post answers my question above and points out a seemingly helpful change in the mapping process that AC has recently made. It seems to clarify the best overall process for mapping.
Can you please help with some of the other questions here? (e.g. which build to look for and how to get it, and some of the issues that Chris is having)?
Also... is Harris emailing everyone else out there to explain that if you watched the video and read the instructions, a change has been made and you need to go back and re-think your process?
