reported KS-19 AAA FLAK and SON-9 ---NIGHT--- tracking BUG

[GumidekCZ]

SON-9 refusing to track and guide KS-19 fire to target when Moonlight is lower than half-moon and lower to horizon.
My test mission: AAA_FLAK_TEST.miz

Mission I share is set to have barely enough moon light - SON-9 will track target when passing by - but instead of firing KS-19 will start to spin forewer:

When you edit the date to 1 day before (14th February) and to time 22:00, the moon light will be degraded to level, when SON-9 will be not able to track at all.

I have asked the team to take a look.
