phobos goes into shadow while not being eclipsed by mars due to inclined orbit

[thomas]

while orbiting phobos, i noticed that phobos gets dark as if it has gone into the shadow of mars even while the sun still has a line of site to phobos, due to the high inclination of phobos' orbit. game time is 1 year 325 days 19 hours 55 minutes 56 seconds. screenshot is showing line of sight to the sun, didnt get a screenshot of phobos with a darkened surface. upon advancing the orbit of the moon around again, it happens with every orbit as if the game isnt factoring the inclination of the moons orbit into its calculations for if the moon should be in shadow.

Updated to the latest version (v2025.11.8.2847) and the issue is still present. upon further testing, this issue seems limited to Phobos but not just at high inclination. It is also shaded too early when passing behind Mars normally, as well as staying shadowed even after passing out from behind Mars. Deimos is shaded at the correct time when it passes behind mars. Of the other moons of other planets that I checked, I did not find any moons shaded at the wrong time. Grabbed three screenshots showing Phobos lit, going into shadow, and fully shaded, all while maintaining a line of sight to Sol.

FWIW I've noticed that vessels also don't become unshaded until well after the visible sunrise regardless of orbit.
