As a quick fix add this option to spacer config - keep_obsolete_spaces = true. But keep in mind that you shouldn't use automigrate when preparing for a production use.
I'll think on a better solution later.

Hi! I ditched automigrate option from the spacer and replaced with an :automigrate() method which should be called after all spacer:space() calls (check the readme for details).
