A few days ago I experienced a strange bug in the first Baldur's Gate - the abandoned house in the area NW of Nashkel (where Drizzt is) opened its doors to me. From there I was able to enter the cellar, and from the cellar a vast dungeon that turned out to be a shadow copy of Dragon's Eye from Icewind Dale. All text, dialogues and NPC names and sounds, however, were garbled. Apparently I was able to enter the house because I had not known to run modmerge on my modded BGEE before putting SoD on top of it, so the CHITIN.KEY file had become corrupted. While this did not change anything in the regular game and I was able to leave the dungeon the way I had come and play on, the garbling affected all mods I had.
I was afraid that I would have to start a new game to get the mods back to normal or ignore them this playthrough, but a fresh reinstall helped. I removed SoD, then BGEE, keeping the saved games folder; installed BGEE again, then the mods, ran modmerge, added SoD - and my saves work perfectly. The mods are entirely fixed, although some left-overs from a few mods I had not liked but had not been able to cleanly uninstall remain, e.g. the Morninglords in Beregost etc., and their names are garbled. But everything installed afresh works. This is good news for two reasons:
1) Those of you who have made the same mistake and put SoD on top of an unmerged installation can rejoice at that you may very well be able to keep playing your old saves with the new CHITIN.KEY. Just reinstall the whole setup.
2) You can play through Dragon's Eye, a large and fairly lucrative dungeon, by reproducing my error and then using the method above to fix it. Unlike me, however, you will get normal text and sound bits, because you can now fix CHITIN.KEY after
you have entered the house. I tried this on another save and it works. To get to this shadow content you can either do what I did - uninstall your setup keeping the games, install BGEE, then the mods, then, without merging, SoD - just back up your regular CHITIN.KEY first so you can put it in the place of the jumbled file later; or simply use my CHITIN.KEY attached here. It may the better option because my file may have been garbled uniquely by the combination of mods I used.megafileupload.com/fv22/-bad-_CHITIN.KEY
Back up your own CHITIN.KEY just in case. I am giving no guarantees that my file will work on your setup, but I pretty much guarantee that even if it does not, you can undo any damage by restoring your old CHITIN.KEY or, at the most, with a clean reinstall. Your saved games are not going to suffer even if you overwrite them, but you should save to a new slot. So the how-to is:
1) Get inside the abandoned house with the "bad" CHITIN.KEY and save there;
2) Bring back the "good" file or reinstall;
3) Go downstairs and play the dungeon.
As a side note, this is not quite
the Dragon's Eye from Icewind Dale. It is, on the whole, easier and I was able to beat it with a level 4 party, although some parts are harder than others. The monsters you will encounter are different from what spawns in the original. For example, you will not meet any Yuan-Ti, Trolls or Lizardmen, but you will encounter some nasty monks, and instead of bombardier beetles and other fauna in the cave levels - undead. Beware of Doom Guards! They will challenge you even if you breeze through the rest. Whether some creatures fail to appear because the in-game resources are absent or for some other reason, I cannot say.
