Incorrect, it isn't. I didn't do my chase missions until late last night so I was able to do chase missions while the new April Session started. It had no progress after I did all three. I was able to make progress in other aspects and nodes, so it can't be with weekend missions. It has to do with Rogue event ninja kills on Saturday I would imagine.

sometimes doing the right mission doesn't count, I was a day behind the rest of my server in some nodes last month because they somehow bugged and didn't count on March 1st for some weird reason, so there's that. Other nodes counted on the same day, and those nodes started counting the next day, so I just chalked it off to in-game bug and weirdness.
