KSP Recall :: Heading Drift Problem
25:12 MET : Finally, the focused Aegis had drifted half a degree to the left.
The Kerbals stopped drifting around, because they are now touching the Aegis - and I'm pretty sure this may the reason she ended up drifting a bit now.
The other Aegis is perceptively drifted. I think my efforts to save CPU may caused some unintentional (lack of) effect on unfocused crafts.
I will try to tackle this down before releasing KSP Recall to CurseForge and Spacedock.
