Unknown Structure Error

Development Programming & Scripting

Hi,
When I try to package my project I get lots of unknown structure errors coming from something with data table row out rows. I don’t get any errors during runtime before packaging and I didn’t get these errors before upgrading the engine version (from 5.4 to 5.5).
I can also tell the the path mentioned in the error is wrong, for example:
“LogProperty: Error: FStructProperty::Serialize Loading: Property ‘StructProperty /Game/UI/Asset/UI_Asset_Widget.UI_Asset_Widget_C:PopulateVariationBox:CallFunc_GetDataTableRowFromName_OutRow’. Unknown structure.” - I can tell the it points to “Game/UI”. The UI folder used to be inside the Game folder, but I moved it out of there.
Anyone knows how to solve this?
