This happened before I freed Hendak so Lehtinan was still the owner at the time. He did not go hostile. The timing was right after I got Lehtinan's permission to 'look around'. I think the bouncers are door-keepers and they must have a script for preventing the the guards going hostile when you talk to them after Lehtinan's blessing. Of course, the bouncers were both dead when I first entered the CC so they couldn't perforn their duties. As for the where, Madame Nin, Rumar, his girlfriend and some commoners went hostile in the upstairs room. Later on when I was trying to free Hendak, some guards attacked me in the arena and the barker in that location went hostile on me too.Oh the thing with the SHOUTS? I have had that happen sometimes when I retreat back in battle where commoners are (none of the mods in question specifically) could be vanilla too. Especially in this scenario, players may be tempted to retreat to prep or something and the guards follow them out. I need more specifics of how and where exactly in the CC it is happening. If Hendak is going hostile, then spells are hitting him.
Incidentally, after Hendak took over the CC everything was fine...
