The crash can be worked around by modifying FFoliageISMActor::Serialize as following code :
void FFoliageISMActor::Serialize(FArchive& Ar) { #if WITH_EDITORONLY_DATA if (!Ar.IsCooking()) // add this if statement { Ar << Guid; ClientHandle.Serialize(Ar); Ar << ISMDefinition; Ar << ActorClass; } #endif }
The packaged game crushes with following error message :
ObjectSerializationError: /Game/P_ISMActorFoliage (0x560D969E43985BE3) /Game/P_ISMActorFoliage (0x560D969E43985BE3) - InstancedFoliageActor /Game/P_ISMActorFoliage.P_ISMActorFoliage:PersistentLevel.InstancedFoliageActor_0: Bad import index 373652847/67.
