Moloch.

Alright, I'll shut up.

There is no movie for carnival, but the Nashkel movie (and chapter change) is shown either on entering Nashkel town or the carnival, whatever happens first.
Other question - does something else happen on those rests, like some NPC talking to you or some assault or whatever type of interuption?

One thing you can try
C:SetGlobal("wm_bgt","Global",2) before you rest your party.

The problem solved itself when I rested several times in a cave in the Gnoll Stronghold, and I got the dream. Still, I think I was supposed to get it when I rested for the first time in a city inn after the start of chapter 2.

By the way, I am officially still fucked. There is a dude named Allister that prevents me from accessing the part of the stronghold when Dynaheir is hidden.
If I try to engage him, he obliterates me.

I have a level 2/2 Fighter/Mage, Imoen (lvl4), Jaheira (lvl 3/3), Khalid (lvl4) and Minsc (lvl3).
I cannot go ahead and grind some more levels, because Minsc is recruited and if I don't rescue Dynaheir reasonably sure, he will turn on me.
So looks like I'll either have to temporarily drop Minsc or restart the game

BTW, I know that this Allister dude comes from a tactical mod, but a level 9/9 Mage/Thief (I looked him up in Shadowkeeper) seems a bit too much for the Gnoll Stronghold.

Update: I have shied from resting OUTSIDE so far, for two reasons

i) I thought I needed to rest inside to trigger the dream
ii) I want to defeat Rhialto the Marvelous in his normal form and I'm not strong enough yet to do so.

But now I tried resting outside as a test, and SOMETIMES, the dream appears. Very weird. It never seems to appear inside (I tried 50+ times).

i) Upon entering Nashkel (and Beregost, and the Friendly Arm Inn, and the Gnoll Stronghold) the movie was regularly shown. No movie for the Carnival, though. Didn't know such a movie existed.
ii) I'm definitely in Chapter 2, and the console command posted above returns 2.
iii) I have not tried a minimal install yet.

Well, here's a new bug. I have arrived in Nashkel and rested inside the local inn. No dream, no new powers. Since then, I've rested several times in Beregost, in Nashkel and at the Friendly Arm Inn. Still nothing. My weidu log is still https://www.sendspace.com/file/n0pbag.

 

Has anyone seen this bug before?

What is the bug?

The first dream is after you cleared the mines, right?

 

The dreams start at the beginning of each chapter. Chapter 2 starts when the party reaches Nashkel for the first time.
