The Division 2 has had a stable launch but bugs and exploits still happen from time to time. One such exploit allowed players to keep getting loot and blueprints from weekly and daily projects, which forced Massive to disable them.
The Division 2 went down for a brief moment on Sunday, 07 April 2019. If you played then, you may have noticed. Otherwise, you probably didn't even catch a glimpse since Massive booted the servers back up mere minutes later and everything was back to usual, except for the daily and weekly projects.
It appears that an exploit allowed players to complete these projects repeatedly, despite them being supposedly time gated, allowing those who used the exploit to get access to rare blueprints and gear sooner than intended.
Neither Massive nor Ubisoft noted anything about banning anyone so it is probably safe to assume those who got more loot than intended will get to keep it. On the other hand, those who were just regularly farming the projects will need to wait for an undisclosed amount of time . You can keep track of the developers' progress in the linked thread.
A bit of a workaround for those affected would be to go and farm the Dark Zones if they want to gear up quickly, but they will have to wait until the fix comes around in order to get the aforementioned blueprints.
As a reminder for those wary of the Dark Zone, loot there does not function the same way it did in the original The Division. Landmarks are more frequent, giving players access to more guaranteed loot that doesn't need extraction, on top of random NPCs now dropping non-contaminated items as well.
Upon potential death, players will only lose a bit of Dark Zone experience and will drop contaminated items they are carrying. In any case, while going to Dark Zone may result in a gank or two, it is still highly lucrative even for those who avoid PvP.
