And I don't mean spiders, mind you, but the kind that make your game impossible to advance.
Has anyone found missing key elements like... ummmm...keys?
I am in my second party/run. In level 2, where the blue stone is, there is a door with one key hole at each side and a teleporter behind it. I remember having placed one of the keys. I can't, for the life of me, find the second key. I am sure this has to be some kind of bug, because I had no problem in my previous run. I'm thinking about restarting 2nd level, but I'd hate to have to do that. :(. Any comments? Thank you.

First, I suggest you mark your post with spoiler or something. At first, I read your post thinking it was just about whether anyone found any bugs, and then you suddenly proceed to give away part of Level 2 in the middle of it.

That said, I don't entirely remember that level, but since you've already done this once anyway, you can't really be spoiled if I link this: http://www.gamebanshee.com/legendofgrimrock/walkthrough/level2.php

It should have the info you need.

Also, no, I haven't run into any bugs. None that I have noticed, anyway. :)

From what I have seen of the game sometimes keys get lost/hidden under things. Try looking under things by picking them up and moving them.

Sorry but I see no spoiler here. I am not disclosing any secrets or ways to do anything. Its just a room with a door with 2 keyholes. What spoiling is that?

Thanks for your answer, though.

I'm sure I won't spoil anything if I remark that keys can also be dropped by dead critters.

hm.. Only seen one so far
Archers can't hit you while you stand in any staircase.

****SPOILER****

in chamber of pits (lvl5 iirc), I dropped down the pit, went afk for a smoke on the stairs and when I came back there were like 400+ frost arrows lying on the ground for me to loot..
