LoadConfig error with UMGSequencerSettings after upgrade to 4.12

After upgrading to UE4.12 the editor shows the following message in the output log window when starting up the project:

LogEnum:Warning: In asset 'None', there is an enum property of type 'EMovieSceneKeyInterpolation' with an invalid value of 'MSKI_Auto'
LogObj:Error: LoadConfig (/Engine/Transient.SequencerSettingsContainer:UMGSequencerSettings): import failed for KeyInterpolation in: MSKI_Aut

I don’t understand what exactly that message means.
How is one supposed to read it, what to do?

Hello haimat,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Can you reproduce this issue in a clean project?
  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?
  3. Could you try deleting your saved and intermediate files before upgrading your project?
  4. Could you provide and code and/or screen shots of any blueprints that may be involved with this issue?

Hi , I understand that you would like to see a bit more information on this issue, but unfortunately I cannot reproduce this with a clean project – in fact, that is exactly my problem I am struggeling with. Also I cannot narrow it down to a certain BP asset, as the error message shown above does not link to a custom BP asset :frowning:

Do you have any ideas what I could try with my existing (converted) project?

Any hint about this issue ? im trying to track it down nothing so far

Deleting saved and intermediate files fixed the error for me.

Hello ,

I am happy that my suggestions helped and that you were able to resolve your issue.

Make it a great day

Hello haimat,

Did you try deleting your saved and intermediate folder to see if this helps resolve the issue?

I am abroad right now. Will give it a try this weekend and let you know then.

I can confirm that deleting Saved and Intermediate folders before upgrading fixed this issue for me. Thanks!

Deleting just the project/saved/config folder worked for me. I’d recommend trying that first to save time if your saved folder is massive.
For reference. My error was LogObj: Error: LoadConfig (/Script/BlueprintGraph.Default__BlueprintEditorSettings)
