hey, i found something else. After getting this message i decided to visit the creator's other maps and to no surprise, i did find 2 rooms on the 2 other maps he created.

SCP-106's chamber

When you spawn, go down the ladder that goes to the control room, break the wall and there will be a small passage in the floor, at the bottom is a short corridor and a room blocked by undestructable lines of voxels. At the wall you can see voxels that are colored to resemble numbers, 0s and 1s, which is, binary. There are 4 rows for 4 numbers, but after decoding, turned out the first number isnt there, probably because i failed somewhere, but here's what i got: (0011011)758

When i checked the update logs of the map, there was more binary in there, which translated to
"That hallway, something lurks down there, I don't know what it is, but I'm not willing to find out."

After flying around with noclip, i noticed a large hallway

It can be accessed a similar way to the one leading to binary on the wall, just break the wall behind the stairs that lead to the chamber itself and drop down.

The second hallway resembles that of 106's pocked dimension with him sitting on a throne at the end of it.
troughout the whole hallway you can hear the audio similar to the third nightmare in 682's chamber

After creating a local copy, the audio was there, named "TDNightmare"

I do not know how to decode this one, i do not even hear any morse (unlike 682's nightmare, where you could hear the morse), and the spectrogram shows nothing (to me at least)

SCP-173's chamber

After you enter the room with the gate, on the left wall break any of the small vents on the wall, there will be a small passage leading to a room with voxels resembling morse code and some strange ones below them (https://imgur.com/a/0dbK2I5)

After decoding the morse i got this:
"f 6e wall"

Sadly nothing like this in change notes this time

I hope this helps with further investigation
There is another 4 digit code in the 106's map so im guessing soon we can find out where to use them

edit: turns out there is more to find in 173's chamber.

After flying around a bit more, i found a youtube link on a wall, to reach it without flight you just have to break the wall in fround of you when entering the room in front of you (when spawning) and you will find a passage. The wall is thick though

I am definitely typing this link wrong as youtube says its unavilable, but here is the wall https://imgur.com/a/HpQMKBu

edit2 (around 1 minute later): turns out i am dumb. The link leads to the nina tailed fox song so i think that isnt really related to this https://www.youtube.com/watch?v=2SwKjxUl1HQ

I'm going to start by investigating 173's chamber, sounds like you've already got a good start.

I also got lazy, but now that a new map is out I might start trying again.

start breaking into vents hidden on the new map, there are things that are very interesting

Wow thanks for doing so much work for decoding a easteregg yall are so dedicated!
