I play on a server with pregenerated world. nothing new can be spawned etc. I need to know a research name of a "exploring The Emptiness" research and all that it connected to it after this one. its not listed on a wiki/doesnt work. creating a new fracture using /ta makefracture doesnt work either on this pregenerated world

I didn't know that was broken with pregenerated worlds, but it makes sense - we currently rely on dimension information being available while fractures are being generated, and I'm guessing that information never gets populated by the pregenerator. Add that one to the list for the fracture rework I suppose...

For now though, /ta makefracture should work as it was designed for these kind of situations. Please tell me:

• The exact command you are trying
• Output/feedback from the command, if any
• The output of /forge dimensions list

"/ta makefracture 1 14676" output was "this dimension is not loaded" from other dims we got twilight forest and aether.

If you didn't provide 2 sets of xyz coordinates in the command before the dimensions, you should do that (and I would need to fix it to give a better error message). If you already did that or it didn't help, you'll have to teleport to dimension 14676 with /forge setdimension <username> 14676, then make a fracture from dimension 14676 back to your spawn dimension (probably the overworld, 0), which should always stay loaded. I highly suggest flying while teleporting to that dimension, as you might get unlucky and teleport over the void.
