LogClass:Warning: Enum ‘/Game/LOE/Components/CharacterComp/System/CharacterGeneral/CharacterClass.CharacterClass’ was upgraded to use FText to store its display name data. Please re-save this asset to avoid issues with localization and determinstic cooking.
Resaving does not resolve the issue. Error likely related to breaking widget content upon project launch - removes widget content without error upon start. This issue shortly begun to surface after upgrade from 4.14.3 to 4.15 - Can not reproduce. Enum file content looks normal (all user content entries still present).
Example, removes inventory layout contents, from main hud - using Action RPG Inventory System Action RPG Inventory System - Marketplace - Unreal Engine Forums
Temp fix, readd InventoryLayout widget upon restart, rename it to Inventory.
