Hello, so in my game player controls located in level blueprint (puzzle), player can move by WASD or arrows, or mouse. Input are fine in editor, but in packaged game after I press button in UI (tip about level), I cant use arrows until I click somewhere with mouse, but WASD works fine. Arrows event conneted to same blueprints as WASD, so problem with arrows event recieving.
Hmmm, this is really strange, I created new project with same UE4 version to share problem, but this project dont have problems with arrows input after UI click …
Looks like its a strange UE4 4.22 bug, you can fix it like I did (After button pressed. Self its default engine variable)
If someone interested in how bug looks like WindowsNoEditor.zip - Google Drive
