Reported Version: v0.2.1 (latest) | Mods: none | Can replicate without mods? Yes OS: Windows 10 Home 22H2 | CPU: AMD Ryzen 9 5900X 12-Core Processor | GPU: Gigabyte RTX 4070Ti-Super | RAM: 48GB DDR4
I initially thought I might be imagining this, or that maybe decoupling a spent stage (two crafts / two burns) imparted a small rotation to my craft, but in Monday's play-session, I saw my craft (and I believe maneuver-marker, to which I was 'locked on') noticeably re-orient itself once the previous stage was released. <<I have video now showing this on a test / dummy craft>>
My best guess is that, along with the moving 'separation indicator' reported here, the game recalculates where the burn "should" have been pointing all along, as if the whole burn was using the engine(s) now available to it.
In the bug-package (craft, save-file), there is a vessel cheated up to 2700km x 2700km circular orbit, with a ~700 m/s delta-v first stage and a planned burn (calling for significant changes to Pe and inclination).
Execute the burn locked onto the maneuver-marker as indicated.
Upon detaching the spent-stage, the marker violently shifts itself by -40 degrees, (305-deg to 265-deg) which also leads to a dramatically different orbital outcome.
<Edit / additional observation (2024-03-25)>
Not even occurring solely when changing from high-thrust to low-thrust… it just happens any time staging occurs mid-burn; for example, I had a Jool craft with a central stack of Lrg Hydrogen tanks with a SWERV engine, 2 radial stacks of the same, and a final 2 radial stacks of tanks without engines (tanks fuel-line fed the radial+engines which then fed the central stack, à la asparagus) and when I dropped the ‘unpowered’ but still spent tanks mid-burn, my trajectory shifted, though perhaps less violently.
