Package unknow cook failure - LevelActon.cpp

Hello AnswerHub,
I know there are so many post about ‘unknow cook failure’ float everywhere… but there are too many unanswer/absent reply and I cannot find my own answer.

There are about 15 umap in this package, I’ve watching the output log. all of my own umap was successful. until log reach what not my creator - LevelActon.cpp and it got error log as show below. I’ve edit the log for my own safety right with “hidden*” ( there are no special characters other than low dash character _ )

I was trapped there, would like to have a help. please?

Are you working with Source Control like perforce?
If so try to check everything out and package then.

I once had a undefined cook failure that got fixed by this.

Best regards,
Max

In 4.08 yes I did use source control but then I stopped use it.
[edit]
I’ve check it, it’s tick off.

Did you get it fixed? I have a similar error. What was your problem?

No, I haven’t got it fix… I had been reinstall everything and redo all work. still thumb down, its hidden somewhere in engine I think. when I build and package single level and its fine. when i package multiply level it haven’t improve at all.
