24573	"""Unknown column"" exception after removing field in migration."	Tomasz Główka	nobody	"When removing field of base class model in my migration and than using `RunPython` with subclass model query I face exception `django.db.utils.OperationalError: (1054, ""Unknown column 'bugapp_person.name' in 'field list'"")`.  It looks like during migrating, current migration  state of submodel does not reflect field removal. Base class is alright though. Additionally, this happens only when at least one extra model with OTO field to base model exists.

This occurs in Django 1.8. I had no problem with any of 1.7.x (1.7.7 recently).  Simplified snippet attached below runs smoothly with  1.7 and should reproduce the error under 1.8.
