Short version: No, there isn't.
The pledge manager has been closed for a while now, so that's not an option. I already reached out to Free League customer service yesterday, and they responded that currently, all the cloth maps are spoken for (which is what I figured would be the case). They said it's possible there could end up being a few extra left over once all fulfillment orders have shipped (including those outside North America, which are just starting to go out), but they won't know that for at least another month yet.
So yeah, I done f***ed up. Argh.
