This is a workaround for the many bugs that plague this quest.
Problem: I can’t find sir Rodzig at the encampment near Talmberg
Solution: He is found either right next (left on map) of the stables of Merhojed, or walking at the rattay castle (where you report to him the first time you enter Rattay).
Problem: I talked to him, but there is no objective.
Solution. There isn’t supposed to be one. You have done everything correctly. Sir Rodzig is not supposed to move away from his location [edit: at the encampment looking over talmberg] which is why this happens. To fix, simply go back to this encampment. it should fade to black and have a cutscene
This is the two bugs that occured to me, and this is how i fixed them. This if for PC. I hope it helps anyone else stuck on this issue.
