Cannot view the stages from one of the projects

[killbill1]

We get the following error message trying to open the jobs from one the projects. All the jobs in other projects open fine. (on the same server)
Noticed that we can't view any stages from this project.

"The view of the job will be incomplete until the missing stage is restored."

This is fixed now by rebuilding the index.

You may have lost the stages in the project. Is it a new import or did you run out of space or did anybody fiddle with the project?

Alternatively, the project indexes may be corrupted.

Before that, can you check whether you can see any stage in the toolbox and also use them in any (dummy) job.
