There are to my understanding several bugs in this quest hence why there’s so much confusion on how to solve the problem. My problem is that as soon as i reach the second wave of defenders and fight for a few seconds a message always pops up saying" too many of your men has died"this happens due to the bandits being flagged as allies instead of enemies.
I am still unsure of what is the cause of this problem that has been in the game since release, i have been able to complete this quest before but now in 1.6 i had to wipe my game after attempting everything to complete it.
Some claim its the bandits in the quest timmy and others say its when you interact with the priest in Uzhitz.
Whatever it is it was gamebreaking and i had to start a new game due to maximum saves.
