Describe the bug

I built a very large SCS in the Aether (https://www.curseforge.com/minecraft/mc-mods/aether) in ATM9 (53x33x50), copied a base into a 128^3 cell, and rebuilt the pylons in the overworld. When I pasted the blocks back to the overworld, the structure pasted in and I was able to move around and see that it had copied in, but within a few moments the server crashed and shut down (my hosting service is Apex Hosting). I restarted the server and when I loaded back in, it had reverted to the moment before I pasted it back. I tried this a couple more times with the same result.

How to reproduce the bug

Build an SCS multiblock in the aether, copy a volume onto a spatial storage cell, build the SCS in the overworld, and paste the structure there.

Expected behavior

The structure should paste in to the overworld.

Which modpack is this on?
The crashlog doesn't show any actual participation of AE2 🤔

p.s.: There might be a worldgen crash earlier in your logfile separate from the actual crash report, can you look for that?

Thanks for replying so quickly. The modpack we are using is All the Mods 9 through Curseforge. I added another file to the gist called latest.log that appears to have some of the AE2 details in it. There are a lot of failed copy attempts because I was trying to figure out what the original pylon dimensions were that I forgot to write down, and the spatial storage cell that contained the structure said that it was unformatted so I had to do trial and error until I found the correct dimensions. I also tried downloading the world from the hosting service to attempt the paste on my local computer in case this was a server ram issue and still ran into similar problems. The structure immediately copied over but I was unable to interact with any inventories other than my own. I was able to place fluix cables on the ground but they wouldn't connect to each other and didn't decrease the count in my inventory. I was also able to destroy blocks in the world but they wouldn't drop their block.
