Firstly, i feel compelled to point out thats not a particularly helpful title to your actual problem. not the issue i expected to see when i clicked in.

my advice, for what its worth until someone with more knowledge jumps in, would be to unsubscribe and resubscribe to the reforged eden scenario. i would also make sure the RE folder got deleted from program files(86)/steam/steamapps/workshop/content/. its gonna be a long number, you might have a few. the right folder will have a preview image for reforged eden, so its obvious.

i once had to reinstall Empyrion entirely to get Steam to update the reforged eden scenario. Steam is not the most realiable application. depending on your internet speeds you might want to wait on that one until someone else chimes in atleast, and be sure to back up your blueprints first.

Hey, agreed the title could definitely have "missing" in it. Thanks for pointing that out.

Tried to unsubscribe and resubscribe. Copy paste with the binary transfer to the server freshly again but unfortunately didn't fix it.

I'm at the very beginning so i don't really mind losing everything but thank you for your response.

I've also did go through the dedicated server guide which also didn't help.

For now, i switched back to vanilla.

I have this nagging feeling i am completely misunderstanding you, so i apologize here

first and foremost, you are saying that the game is telling you it requires carbon substrate to craft the constructor in reforged eden? that is how i read that first sentence and that is a problem because reforged eden actually requires IRON to construct it, not carbon substrate like vanilla, 5 iron is what it takes. I just want to be clear.

just to verify, when you launch reforged eden does it report build 51? it should show when loading/ starting the game, you can also open your inventory(tab) in game while playing reforged eden and it will say inventory(build 51) upper left, over your personal inventory
