Games Halo 5: Guardians

The title is pretty self explanatory but I can’t make a prefab without my game crashing.

What do you mean by “prefab”? A custom match? A map in the forge? A custom mode of an existing variant?

A prefab in Forge. Where you combine objects and can save it but everytime I go to save it, my game crashes.
