There might be a newer topic on this issue, but I couldn't find.
I have a problem with Doemenels. I accepted their last quest, now nobody likes me. I thought that I should be able to inform Knights about their plot, but there is no way to do it. There is not option to tell this to anyone with a name in their keep. This is first huge hole in factions system. Another is that even though I killed later every single Doemenel, failing the quest, everybody still claim that I'm Doemenel lover.
This is weak. If other factions didn't like the traitor, it would be fine, but there I have no option to warn others about plot to frame Dozen into murdering Knights general and noone acklowledges that I killed mob boss, this is just lazy from developers.
