Ok this my mod load order for Xbox One: Unofficial Skyrim SE patch

Alternate Start

Wet and Cold.

Sheogorath's Cheat Menu

Potion of Unlimited Leveling

Dovahkiin Keep

Routa

Adventurer Chests

Unlimited Rings and Amulets

Cloaks and Capes

Those are all that I have and it crashes after the first Dragon, am I doing something wrong.

Alternate start should be at the bottom, not the top.

What is Routa for kind of a mod and does what?

I think the Unlimited Leveling mod needs to be at the bottom just above the Alternate Start or loaded last.

Also, check the descriptions for each mod just to see if the mod is compatible e.g the Oblivion Gates mod are not compatible with the Open Cities Skyrim mod, with other mods or not.
