If a model X explicitly defines a GenericRelation to act as the reverse end of a GenericForeignKey from model Y, then the sql generated by ./manage.py reset game will generate an extra DROP TABLE app_Y for each GenericRelation.
I believe the cause is in django.core.management.get_sql_delete, in the many-to-many section around line 307 or so. Model X apparently treats a GenericRelation(Y) as a ManyToManyField(Y) here. This might be appropriate (I don't know), but either way collecting these tables in the set() created above would uniquefy them and solve the issue.
