Finding Alien challenge arena

[DÖGÖXD]

I'm having a big issue....
I've already killed all bosses except Atlantean worm and that's because I cant find the alien challenge arena scene for the merchant summon item....
I know they are quite rare but i loaded up a new(first) game with default settings so my world is not that overly big.
I've read online that they usually spawn at the rim of the biome ring or in those small bubble biomes scattered close to the border. Ive looked anywhere from 900CD to ~1100CD including the the pit between the crystal biome and the passage
there are literally 0 crystal biome scenes all i'm generating is boulders and caves
i did find a few "alien city" tiles or what ever they called but they were very small with a few breakable crates and nothing else
Is my seed broken? is my world too small to generate these?
it feels a bit odd having a mandatory area for completion not spawning at all...
am i approaching this the wrong way?
my explored map for reference

It took me FOREVER to find ONE in mine. Even with a completely morphed world that looks like a wasteland, I still could never find it for hours until I found ONE randomly. The worst is that I followed the coordinates range around all of my world. It's so rare.

I don't think your seed is broken. It's just very rare for reasons. A world will always generate at least one... I don't know how many are supposed to be generated but the world I was in, I only found one. You have to be infinitely patient. Try more than one map.

what makes it even more frustrating is that no other shimmering frontier scene is generating as well
I suspect that something with the world size just makes it impossible to spawn, cause i keep getting relative biome scenes where shimmering frontier scenes should generate such as
ancient cities, mold dungeons and volcanoes all spawning withing SF regions where i should expect SF specific scenes...

care to specify how far from the core did you find it and was it well within SF biome or at the edge?

Ya, there's a ton in my pre 1.0 map, but I've not seen any in my post 1.0 map either.

Every maps (post 1.0) should be large enough and yeah, your CD seems to be about right. I honestly could not tell you more because I searched my whole shimmering region and only found one in there by luck after a while. It's rare, according to information.

My advice: Generate a new world to explore. Biome Chaos, OFF. Ores, ANY. Tunnels, OFF. Chambers, OFF. Rivers, OFF. Lakes, EXTREME. Pits, OFF. (as they seem useless in this context.) I used EXTREME for ceiling holes for maximum lights. It's nice.

Prepare a boat, you'll need one. You will need to search for the bosses to open the wall. It is easy since you will have a total lack of land. (If done right). Then you search all of the big shimmering circle and make sure you go all around its width. Good luck.

tbh i started exploring and mapping the entire SF biome, I want to confirm or deny that with default settings you can have a bad seed which is a problem for new players like myself
I already mapped desert SF and about to finish jungle SF so far 0 scenes.
I wont give up on this map just yet

It's less about giving up and more about "using a new map for exploration" while you keep your main map as your home base. IF you need it, the advice may help you.
