Another player claims to be having the same issue on the forum. They posted in the thread I started, so this might not just be limited to me.

Yes I did all those steps and I always check the ai module after entering/leaving the core to make sure the settings are correct.

The turret is on an elevated flat platform on my station so im not sure what it possibly could be running into. You can pilot it just fine and it can turn in all directions other than straight down.
