Crash upon launch

Hello there! I have recently started to play around with the dev-kit. I have been trying to replicate the industrial forge, just making it smaller.

I made a new mod folder like shown in this tutorial: - YouTube
I then used this tutorial to replicate the industrial forge: HOWTO: Add new structure variants - ARK: Survival Evolved - Unreal Engine Forums

When I run the mod in the devkit it works fine, but when I try to create a new singleplayer world with only this mod it crashes upon start. Any idea what I might be doing wrong?

Edit: This got solved! I missed a file I was supposed to link.

what did you forget I’m starting a new mod and can’t remember what I had to do … when I start a new game it instantly crashes. I linked map to the primal data, added the game mode to the primal data what else did I miss?
now that works but the items are not in game

I just deleted my project and refollowed the tutorial on this forum step by step and got it working.
