What is the issue/bug you have encountered? Give us a short description.
Turret starts spam shooting even though all of the targets are dead, it then spins around as if idle but it keeps on shooting in one specific direction. This usually happens in some modded dimensions (not 100% of the time)

How can it be reproduced?
Not sure but I've had the most success on some advanced rocketry planets or custom dimensions from just enough dimensions

I've recoded the way a turret targets entities somewhat and fixed some issues. I cannot reproduce this in dev, so I assume it is fixed there now.
I'll close this issue now. When beta 4 is released and the issue persists, please open up a new issue.
