Thanks for playing through. As usual, anything that's not specifically mentioned is fixed/addressed.
No journal entries in anything I've tested so far except Icelus' Iron Modder entry. Their absence was very conspicuous.
As mentioned in chat, I think you've just been playing the stuff that happens not to have entries. They're there when appropriate. If you or anyone else know of specific incidences where they should be there but aren't, please do mention.
Considering I could tell Ceilie he looked rich and have him laugh and invite me to attack him in front of everyone if I dared, it was a little anticlimactic that he was only carrying 16 gold. Does anything happen if you kill him without setting off the Copper Coronet (say, by using the Ring of Human Influence and escorting him into the back after you've killed Lehtinan)?
He now has a bit more money on him. Nothing special happens if you kill him out of sight, except he won't turn the whole Copper Coronet hostile.
How does he get new victims if the only way to get him to lend money is to threaten to sic the guards on him?
He approaches people (or his thugs direct them to him). I've modified the dialogue slightly to have him mention this.
There is no Moiya anywhere in the slums, which stalls me right at the beginning of his quest.
Sometimes she spawns, sometimes she doesn't. I think I've really fixed it this time.
Swishswishswish, hm? All Mae'Var's thieves are hidden in the shadows, I take it? Very nice touch.
Thanks. Out of interest, has anyone fought Mae'Var now? I'm concerned that tons of backstab damage will be too much for a chapter 2 party to take.
Right after Xzar killed Lucette--and I mean right after, before he said anything more, while he was standing there--Meronia appeared to collect Jaheira for her standard return to the Harper Hold. Jaheira, incidentally, offered not a word of protest to my selling out Lucette.
As discussed, there's now a delay before Meronia spawns. Hopefully everything works okay with her spawning in all situations now. If someone other than me can confirm this when I put out a new beta, that'd be great.
The Harpers seem oddly quick to trust, considering the neutrality of "A mage sent me to retrieve his captured companion." I wouldn't expect them to open up about their plans until you indicated more clearly that you wanted to betray Xzar to them, with something like, "A Zhentarim mage wanted me to infiltrate your compound, and I played along so that I could tell you about him."
After receiving the bird/assassin from Meronia, all the Harpers on the first floor still address me like I'm being set up to sneak upstairs, talking about the guardians and their amulets. Even Meronia acts like there was never a plan to set you up--"Rylock evidently considered it wise to allow you in"? That might make sense if they have a backup plan for if you betray them to Xzar, which I don't know because (see below).
Berinvar and Meronia also seem remarkably unsurprised when I tell them about Montaron, considering they were setting me up and didn't expect me to suddenly tell them the truth.
My conversation with Lucette after she kills Xzar is effectively unchanged from when I was acting as a dupe, except for the loss of a couple of my conversation options. I still have no choice but to act shocked ("You mean Meronia actually meant you were going to kill him when she said you were going to kill him?") and Lucette still chides me as if I'd tried to help Xzar against the Harpers, instead of being allied with them.
Xzar sent me back to find out what really happened to Montaron, and I found the door unpickably locked and the door guard gone. Some part of this may have had to do with Jaheira's departure right after Lucette died.
I've yet to address all of this, but will do so when I rework the quest dialogue so it (hopefully) sucks a bit less.
