I have been having major problems after switching to 4.18. Destructible meshes seem to be completely non-solid in packaged version of the game. I have added “ApexDestruction” in both the “Modules” and “Plugins” sections of the .uproject file as well added it into PublicDependencyModuleNames in [ProjectName].Build.cs. The collision seems to work perfectly in the editor. I am also having a lot of other problems in 4.18 such as AI Controllers missing for enemies (player owned characters still seem to have their controllers). The enemy characters themselves seem to be completely collapsed on the mesh origin as if they didn’t have a skeleton (again, player owned ones are fine). Async scene setting in the mesh physics was disabled default in the project settings.
I’m also having this issue. Destructible mesh works fine in-editor but in packaged build they just float there with no collision
