My Jenkins 2.32 installation with BlueOcean beta 1.0.0-b12 plugin tracks a project with a Jenkinsfile. When I start a build (with the "play" button in BO) it either never appears in the list, or appears and then disappears. I can type the URL to see its progress, but the display is usually stuck at some early stage of the build. At the same time in the classic interface I see all builds and logs, including the coloring of passed stages.

The BO list of builds might catch up some time later - e.g. in the morning I saw only 3 builds while there were over 30 in reality, and in the evening I saw all 35 - but the 36th+ started afterwards did not show up.
