Trigger box not working in packaged game

Hello, I have a trigger box in my level.
In level blueprint I set on actor begin overlap it shows a widget. Very simple.
When I lounch the game from editor it works, when I package and run the packaged game it not
works. Why ?
Thanks.

Please someone who could help me!!

Hey there @Mandrake1983! How are you testing the collision? Does your test have any editor only code? Stuff like debug lines only appear in debug builds and in editor and not shipping builds. Could I see the BP/Code?
