Build failure 4.8.3 Please help

I’m pretty new to actually building my projects and I am receiving an error when I attempt to build my university assignment.

Here is a link to my cook log.

Any assistance or insight with solutions for this would be greatly appreciated.

Hello,

When you have some fail, you should look at the error summary at the end of the file. Search for : “Warning/Error Summary”

The first line (and the only error) is :
LogProperty:Error: UStructProperty::Serialize Loading: Property ‘StructProperty /Game/ThirdPersonBP/Blueprints/MyBlueprints/BP_Weapons/BP_Weapon_Ranged.BP_Weapon_Ranged_C:Ammo’. Unknown structure.

So it seems that the type of the variable Ammo in BP_Weapon_Ranged reference a structure that may have been removed or a link is broken and you should recompile this blueprint to be sure.
