# django__django-13265
# Loki Mode Multi-Agent Patch
# Attempts: 1

Based on my knowledge of Django's migration autodetector, I can generate the patch. The issue is that `AlterOrderWithRespectTo` creates the `_order` field, but `AddIndex` operations that reference `_order` are being generated before it. The fix needs to ensure proper dependency ordering.

Let me reconsider the Django codebase structure and provide a correct patch:

Actually, let me provide the correct fix based on how Django's autodetector actually works with dependencies:
