Hi ~ I don’t want to hijack someone else’s thread, but this looks similar to something we are running into; with this error only occurring during MPCook:
LogCook: Warning: Content is missing from cook. Source package referenced an object in target package but the object was stripped out of the target package when saved.
Source package: /Game/Materials/Utils/Blueprint/BP_Sky_SeasonAutumn
Target package: /Game/Materials/Utils/Blueprint/BP_Sky
Referenced object: /Game/Materials/Utils/Blueprint/BP_Sky.Default__BP_Sky_C:NiagaraLensFlare:NiagaraDataInterfaceOcclusion_0
We merged in the two change lists that you mentioned and picked up an additional error:
LogCook: Warning: Content is missing from cook. Source package referenced an object in target package but the object was stripped out of the target package when saved.
Source package: /Game/Entities/Harvestables/Brambles/Festivals/BP_RainbowCornStalk_01
Target package: /Game/Entities/_Templates/BP_BaseActivity
Referenced object: /Game/Entities/_Templates/BP_BaseActivity.BP_BaseActivity_C:DefaultStateSFX_GEN_VARIABLE
We started from 5.4.4, I’m wondering if there might be another change missing/other things we might try.
In case the information is helpful, we also saw these errors on some properties marked with UPROPERTY(Transient) ~ adding DefaultToInstanced to the class definitions seemed to clear out those cases.
Thank you,
Richard
