It seems that enabling the auto aim setting, even briefly, will permanently break the "turn to cursor" setting. By that I mean no amount of inverting the behavior in the options will change it, and the game will be stuck thinking that you are using tank controls by default. There is kind of a way around this if you're fine using the toggle setting to switch between them, but you will have to do this at the start of every fight, and you will not be able to hold shift and release to go back and forth between the two modes.
I'm currently trying to figure out a way to fix this, but so far nothing has worked. And no, I don't know how to replicate it as I can't restore regular functionality in order to even attempt it.
Edit: Okay, it seems like the issue gets locked to a specific ship. Every other ship in my fleet is completely fine and functions as normal, it is only my flagship that is incapable of turning to cursor.
Edit2: It isn't just that singular ship, it is all *instances* of that ship. Making a completely new game does not fix it if I spawn that ship in and attempt to use it. Reinstalling both this mod and the the mod that ship is from had no effect.
I have no idea how to fix this at this point, beyond completely reinstalling starsector.
EDIT 3: FIXED IT. IT WAS SOME RANDOM HOTKEY FROM FLUX RETICLE(?). If you have this issue press k.
