Anyone noticing Sparrows are inconsistent now?

I’m noticing instances now where my sparrows just won’t pull. Other times they work wonderfully. Other times, a perfect frontal aspect shot, the enemy just does the most limped wristed sparrow roll and my missile fails to proxy.

Other times. The sparrow just refuses to actually do anything and stays still. Again, even in frontal aspect shots where the enemy is completely unaware.

What’s going on?

Which aim7? They have had some guidance quirks for a while so i would not be surprised if they still existed.
