Cadaver

Hi, I'm new here and this is my first topic, so please try to be indulgent : P Ok, so here is the problem: whenever I try to explore firewine ruins I get into wyvern's lair. There are some characters from firewine ruins like Lendarn, ogre mage, some kobolds and so on, but there is no dead knight so I can't finish quest with armor. I tried to use all of three entrances and I always get into wyvern's lair. I used console to get there and still same thing. So I tried to get to the wyvern's lair and...game crashed, so it looks, like one of mods messed up these two areas. I play Baldur's Gate Trilogy (v1.07) with mods:

The Darkest Day v1.12
Shadows Over Soubar v1.13
Check the Bodies v1.11
Tortured Souls v6.10 (BP version)
Region of Terror v2.1
Dark Side of the Swords Coast v2.15
Northern Tales of the Sword Coast v1.71
The Secret of Bone Hill v2.40
The Grey Clan Episode One: In Candlelight v1.8
The Lure of the Sirine's Call v9
BG1 Unfinished Business v7 for Tutu/BGT
Sword Coast Stratagems v12
BG2 Herbs & Potions Add-In
Ajoc's Minimod Weidu v1.6
Desecration of Souls v2.61
The bigg Quest Pack v2.02
Tower of Deception v2
Ding0 QuestPack v2.3
Dungeon Crawl v4
BG2 Unfinished Business v1.8
The Big Picture v177 [v177a] + BPv177 TOB Trigger Fix
Ascension v1.4.22
Sword Coast Stratagems II v8
Baldur's Gate Trilogy Tweak Pack v8 (some of tweaks but not all of them)
Ding0 Experience Fixer v6
BP-BGT Worldmap v7.1


It's the second time when I use this configuration and second time when this happens.
Next weird thing-my weiDU.log (I don't know why it's so small):

// Log of Currently Installed WeiDU Mods
// The top of the file is the 'oldest' mod
// ~TP2_File~ #language_number #component_number // [Subcomponent Name -> ] Component Name [ : Version]
~SETUP-XPMOD.TP2~ #1 #10 // Brak PD za uczenie sie czarow
~SETUP-XPMOD.TP2~ #1 #11 // Redukcja PD za wykonane zadania -> Zredukowac do 75%
// Recently Uninstalled: ~SETUP-XPMOD.TP2~ #1 #1 // Redukcja PD za pokonanie wrogow -> Zredukowac do 50%

Any ideas? Thanks in advance ; ) (and sorry for some grammar mistakes)
