close #26

Hey!

Thank you for looking for the root cause of the problem. I actually just pushed a commit that is nearly identical to yours, but it also fixes some of the overly complicated syntax to define num_bases that was in the adapter module. I'm going to reject this commit just because commit 3f185cf is essentially the same fix but otherwise it would be merged.

Apologies for the inconvenience!
