Pretty much as the title states.
After opening the dgn file with OBD (CE Update 6) and microstation (CE Update 13) to perform some printing operations, I closed and reopened it with OPM (CE update 7) to find the Pipelines in the dropdown selection area of the combobox in Standard Preferences for Piping Component toolbox were gone. I then checked the pipeline manager as well as the explorer and both reported the pipelines were actually still there. I tried to import the pipelines back to the model, but was told that the pipelines were already existed and nothing was imported. This seems like a bug to me, Is there a way to fix it?
