I have 8 lava lamps, but I only have identified 6, the other two no matter how hard I search, I don't know which knuffel room they were in, could you help me with that?

I am afraid the only way to know in which room you put them is to go through your Knuffel and look at each room.
I have no other way to know in which room you put them.

I can only help you look through the knuffels you have made public.
Here's what I found so far:

Draconis! has at least one (remember that if you put more than one lava lamp into the same knuffel room, they overlap until you start moving them. So go into the room itself and start moving the lamp to see if there's only one, or if more than one is stacked on top of each other)

Aang! has at least one

...

And that's all I saw in your public knuffel.

Do you have any knuffel sitting in a trade somewhere? If you send a knuffel with stuff in their room into a trade, nothing is taken out of their room until the trade is complete -so a trade that isn't complete is a great hiding place.

Check your trades for knuffel, too.

Hopefully you found them!

The last thing I remember is removing them from this room:
knuffel.php?i=DAD5CC9C
and later I didn't know where they were, I don't know if they deleted me because of a bug or I don't understand, but in my inventory it does indicate that I still have the 8 lamps and I already searched all the rooms for my knuffels...

So, I looked into it again, and I can actually see where your lamps are. Opps Didn't know starkad had included that in the admin panel for me.

Your lamps are with the following Knuffel
knuffel.php?i=74311503
knuffel.php?i=E50E3E33
knuffel.php?i=6F329B81 2x
knuffel.php?i=74311503 3x

I suspect that for the last two Knuffel that have two and three lamps each you have stacked two lamps on the same position, so only one is visible.

everything is left!!! thank you very much firn!!!!
