I've experienced the following two bugs in FNV which are minor but irritating. The first one is at the Arena at the Fort. When I did all three arena fights, each time there were NPC legionaries around the arena who would shoot at my opponent and kill them, leaving not much of a fight for me. I'm pretty sure this isn't supposed to happen. The Legion is now congratulating me for killing an NCR ranger in hand-to-hand combat even though I didn't do it myself at all. How can this be prevented?
The second bug, a very small one, is at the King's building in Freeside. In the room where you meet the King, one of the NPC Kings members is on a stage and dancing. He only did this the first time I went into that room. Every time I've been back, he just stands on the stage idly. Is there a console command to fix this?
Here's my load order. I thought Mojave NPCs might be the cause of the Arena bug, but its description doesn't say it adds any NPCs around the arena. I haven't been able to test the Arena without the mod as now I can't do anymore fights.
