You’re likely referencing a blueprint that no longer exists or has been renamed.

Double check all your references in your modded blueprints and make sure they are pointing to valid ones.

Also make sure your configurations are valid. E.g. don’t make a loot item set with null values.

If you can’t trace the fault… delete your files and start again.

Ah ok it is pro lye because I deleted the 3D model file off my computer

JasonFJ i set my dino model back to dodo (orignal) but it still crashes when i go in game do i have to remvove all of ti and follow ur tutroial again?
