I've been trying to do Tipheret's core suppression twice, and got an amber midnight both times, I tried to cheese the first with backward clock, it did nothing, so the second time I tried to actually fight it but lost a lot of employees, as a last resort I tried to backward clock it again, and it did nothing again
Is it an intended mechanic or just a bug ?

I haven't played in a while, and when I restarted the game, every DLC items (skins, building stuff ect) was missing, be it from previous DLC or for new ones that weren't released back then (but that I still got due to having the ultimate edition)

Is it a common bug, and is there a way to fix it quickly without having to send a ticket to the support ? I'm playing on Steam
