Invalid Skill Stage? I have no idea what I did wrong.

So toward the end of October I got the email that many folks probably got saying "Hey, still time to create a skill for October!" So I did. Everything tested and built, and submitted. Waited. Finally got feedback this morning (a day after the deadline :-/) saying that I had issues, one of which was apparently "Invalid SkillStage"? But more on that in a second. It told me I should go build my interaction model.

Which I tried to do. But attempting to build told me that I was in the certification process, and would have to withdraw from that in order to build. Which I did - thus no longer having a link to the original message.

But....then my build works fine. No reference to invalid skill stage or anything like that. In fact, no amount of googling is giving me any reference to an error like that.

Should I resubmit? I'm wondering now if I spaced out in copying the error message and that's not really what it said. But that doesn't change the fact that when I build, it tells me no errors, so I'm not sure what I'm supposed to do next regardless of what the actual text is.
