23069	Can't rename model with ManyToMany relation	Jeroen Dekkers	nobody	"Given the following models:

{{{
class Model1(models.Model):
    field = models.CharField(max_length=10)
    many = models.ManyToManyField('Model2')


class Model2(models.Model):
    field = models.CharField(max_length=10)
}}}

If I rename either Model1 or Model2 to Model3 I get the following error when running makemigrations:

{{{
CommandError: System check identified some issues:
