**UE 4.18.3** Good day everyone. We have problem with _GarbageCollection_ in packaged game. After 0.5 -1 minute game crashed. And show this message: **Fatal error: [File:D:\Build++UE4+Release-4.18+Compile\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\GarbageCollection.cpp] [Line: 1374]** When we use UE4.17 we do not have this problem. I am trying to fix this problem since last week. That is result of my research: **Case 1:** Widgets cause this problem. In log I can see messages like this **LogGarbage: Warning: Disregard for GC object CanvasPanel /Game/EOTBX\_Library/WayPoints/Base/W\_Waypoint.PLACEHOLDER-INST\_of\_W\_Waypoint\_C\_0:WidgetTree\_0.CanvasPanel\_73 referencing VisibilityBinding /Game/EOTBX\_Library/WayPoints/Base/W\_Waypoint.PLACEHOLDER-INST\_of\_W\_Waypoint\_C\_0:WidgetTree\_0.CanvasPanel\_73.VisibilityBinding\_1 which is not part of root set** In this case GarbageCollection do not like Bind function GetWaypointVisibility. ![229078-pic-01.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/2/6/7/26703b374f3c87e25e6e71cc35b3a3b0539b76be.jpeg) ![229079-pic-02.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/4/4/3/443cbb1b3132a763d69b5d315bff012b09a10854.jpeg) In this function we use reference on _WaypointComponet_( Parent Class: _SceneComponent_). Usually we add this component to some simple actor blueprint. If I remove reference on _WaypointComponet_ from function and live this reference in widget it still call the same error. But when I remove reference from widget it fix problem for this widget. Unfortunate reference on _SceneComponent_ is not one problem. **Case 2:** **LogGarbage: Warning: Disregard for GC object TextBlock /Game/RingMenuConstKit/WB\_RingMenu.PLACEHOLDER-INST\_of\_WB\_RingMenu\_C\_0:WidgetTree\_0.DescText referencing TextBinding /Game/RingMenuConstKit/WB\_RingMenu.PLACEHOLDER-INST\_of\_WB\_RingMenu\_C\_0:WidgetTree\_0.DescText.TextBinding\_1 which is not part of root set** In this case GarbageCollection do not like Bind Variable _ItemDescription_(::Text). ![229081-pic-03.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/e/4/3/e43661b2369062f22eb209267738b569a02a5a6a.jpeg) ![229082-pic-04.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/d/7/6/d762a251b7001188189755040c98954326c989d1.jpeg) And this internal variable is changed only in one function which have reference _SelectedButton_ on _WB\_MenuButton_(Parent class: _User Widget_). In this case I have no idea hot to fix it. **Case 3:** **Warning: Disregard for GC object MediaPlayer /Game/EOTB\_X/VIDEOS/NewMediaPlayer.NewMediaPlayer referencing MediaPlaylist /Engine/Transient.MediaPlaylist\_4 which is not part of root set** ![229084-pic-05.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/7/a/b/7ab20c1d098303ea1363866e8696ddaa83f68a2c.jpeg) Have no idea what is wrong with that. **I will be appreciate for any help or advice how to fix it.** We use a lot of widget so re do all of them takes a lot of time. We do not have any problem in version 4.17. Maybe rules for widget was changed.??? ---
