Cooking is not deterministic for Destructible Meshes

Cooking is not deterministic for Destructible Meshes. Can be tested by doing a release/patch of Destructibles map in Content Examples. Destructible Meshes that have not changed will show up in the patch.

1. Create a new project based on Content Examples in 4.16
2. Follow the steps in Releasing Your Project
   • Select the map "Destructibles"
3. Follow the steps in Patching
   • Select the same map as above
4. Unpak the .pak file in Saved\StagedBuilds\WindowsNoEditor*projectname*\content\paks with the command UnrealPak.exe pack-name.pak -extract path\to\extract\to\
5. Notice although the destructible meshes have not changed, several (all?) are included in the extracted path
