My game works fine in the editor. But when I launch it when I packaged it, it instantly crash and say :
Assertion failed: !Obj->HasAnyFlags(RF_NeedLoad) [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Engine/Private/Animation/AnimCompressionTypes.cpp] [Line: 403] Failed to load AnimBoneCompressionSettings /Engine/Animation/DefaultAnimBoneCompressionSettings.DefaultAnimBoneCompressionSettings in AnimSequence /Game/ragdoll_system/character/animations/locomotion/tps_jump_land.tps_jump_land
