I am still experiencing this bug.
I have been able to start merovingian archive mission 4.3.1 and complete it several times (by just recycling the ticket) but I can't start the next one (4.3.2).
I've been to every single hardline in all the districts and I have been trying to start this mission over several days at different times of day. No luck.
I don't believe the bug lies in the fact that many people are doing it, it is either related to the character or the mission building (if it is a specific one, I don't know if 4.3.2 needs one or uses a random one nearby).
Please devs have a look and try to fix it? I'd love to get my trench!
