I spent my whole day yesterday to figure out and look in the internet why Trigger and collision boxes not working in the packaged game but do work in Editor. All of them work fine but since I changed my characterBP name, all new ones I made work in Editor but don’t work in the packaged game. just tested a trigger box, placed in the world, in levelBP event begin overlap to character and that to play a sound at location. as simple as that. works fine in the editor but when I build all and package it doesn’t 
what could be the issue here?!
Hey @Benyamin3000, I would start by deleting all of these folders: Binaries, Saved, Intermediate, DerivedDataCache. Then regererate visual studio project files and do a clean build. Since this happened when you changed the name of a class it might be an issue with previous compiled files not updating.
If this doesn’t work, then I would recommend debugging the packaged build. For this you would need to build a DebugBuild and attach visual studio to the packaged build process when its running. The option to do this is under the Debug option at the top of VisualStudio interface.
By doing that you can debug your packaged build with breakpoints in visual studio, the same way you would do when debugging in the editor.
Hope this helps
