Landscape Texture is missing after packaging

After I package my game the only texture missing on my game is the landscape, instead of the texture I see a cheaker board black and gray. I went online and tried to find the answer but I still dont have success.

Things I have tried:
-Change the texture assets to Shared Wrap
-Downsize the mats
-Building a new landscape
-Open the project on a new project

Please help me Ive been stuck on this project for a while and this is the only thing holding me from releasing my game!

I don’t have a foolproof answer, but you can try texture painting on the landscape. This was the only thing that resolved the problem for me. Look up a tutorial for UE4 texture painting if you don’t know how.
