The spoiler doors are horrendous. Walking out of them 3/4ths of the time triggers a trap because the NWN engine still registers you as trying to reach the ladder in the other area you transitioned from, and walks you through them as soon as you transition.
Also a trap near the bells is covered in dirt VFX, and if you step on the
dirt but outside of the red area, it triggers and is more or less invisible on the NWN screen.
The sideways and angular // style traps near the end will fire automatically in some areas if you're not even touching them, showing the spikes shoot up through the non-red area of the walkway and that you triggered them.
Another bug is the dogs seem to either de-spawn or die during the first attempt at the quest after a reset and not re-spawn for any other attempts, this results in anyone after loosing 2 gems no matter what, I've gotten 9 gems twice now and lost 2 of them when I turned it in for no apparent reason after not hitting any traps.
Also, please remove the dogs, they cause way too many stupid problems, such as auto retaliate, path blocking, making it impossible to use the picture or pickpocket test. It wouldn't be bad if most of the areas you are walking in are only wide enough for you and nothing elss but as they are, the issues it causes are bothersome to say the least. Im sure you can find something else to replace them.
If the dogs see you, it requires creative methods around them. While I agree many of the trapdoors are poorly placed, there are many ways to neutralize the dogs.
To help this thread: Please re-examine the trapdoor placements. Some of them are just unnecessarily awkward and awful.
