It was happening on Catskills before the publish that turned off guards in faction cities. After the publish guards would randomly spawn that if poisoned or hit in any way by a red character will do a one hit kill on ya, but the mass number of random nobles spawning there could die without getting us guardwacked. (unlike previously we had been regretting our actions quite often)
I have not TRIED to get guardwacked since I have seen this post though.
If I need to be more clear let me know. I'm not sure I am getting my point across
