[1.6.0b2] Invisible Assassin Lord

[Zizzo]

I've done the lost merchant quest twice now in the betas, and both times the Assassin Lord was basically invisible. He was still right where he was supposed to be and would respond as usual, but that's probably gonna confuse new players. (I'm assuming this is a side effect of the apparent new NPC AI behavior of "always turn on all your sustains immediately"; the Assassin Lord is probably kicking into stealth mode, and players at that point aren't likely to have high enough stealth detection to see him.)
