I've noticed the available standing available through my syndicate sigils, as displayed on the console to the left of the navigation console, depleting faster than expected for the past few days.  After testing, it seems that: 1) For syndicate missions of the syndicate whose sigil I'm wearing (in my case, Red Veil mission with a Red Veil sigil), the standing gained through the sigil is deducted from the daily standing cap as normal but the standing awarded for the mission itself is ALSO ded
