Since the first release candidate for this version up until the stable release (0.12.11), there seems to be a breaking bug.
When holding right mouse to set an attack distance, the ship properly moves into attack position.
However, once it's reached attack position, it will not keep updating its angle, its angle will stay the same over time, not tracking the enemy, while still following the enemy and keeping requested distance.
I am aware of the setting related to the grid-relative attack angles. These settings have always been turned off for me, I even tried turning them on and off.
This happens consistently, with any kind of ship, across both of my machines (both updated using auto-updater). It worked fine in earlier versions.
PS Love this game!
EDIT: It just got fixed by removing my Cosmoteer directory in My Games. I started as new game and the problem is gone. The best case scenario is that an RC version screwed up my settings. But that's just a guess.
