for SM Bounty, anithinks reported an issue with doyens not paying off the bounty in different regions in 2011 ( although this should have been fixed already in 2010, latest version )
for Hear no Evil someone posted:
"I killed off entire cities without getting caught at one point with this. There was only one problem, I'm not sure if it was just me or whatever but when I'd get my crime gold up i could not talk to guards (not a big problem, i never do anyway) or if i walk near a guard they attack me"
I think he's actually describing vanilla behaviour here, don't they simply attack instead of trying to arrest you when the bounty is over a certain amount? or maybe he had already resisted arrest.
