So I managed to finish PESTILENCE side quest without losing anyone to the sickness. And I started to notice some weird things happening, as listed below:
- Matthias lays down on the ground without animation.
- When I talk to Matthias, infinite loading happens. Must force quit the game.
- Sir Radzig cut scene failed to trigger.
- Sir Radzig dialogues are not logical ( Reported to him that Merhojed is taken care of, Radzig acknowledged all people are healed. Requested me to stay because he has something to say. Talk ends. Then when I talk to him again he asked about Merhojed and ordered me to heal the sick people.)
- Sir Radzig ordered me to meet the merchant, but there is no marker or anyone suspicious in the inn of Sasau. So the main quest cannot be continued.
I read through the forum, people having the same problem decided to ignore. And there is also a workaround for the cut scene, but then I must give up 6 hours of playtime. (It’s a mercy that I have all my saves backed up)
Personally I am still looking for a way to reactivate Matthias but no luck.
