"Unknown Parts Module" error after removing Docking Port Alignment Indicator mod

[maddog59]

A while ago I installed the "Docking Port Alignment Indicator" mod, but did not find it very useful, so I've uninstalled it. Now all of my ship files in the VAB that have a docking port on them appear in the 'Open' menu with the error message "Unknown Parts Module" under the part count and cost line. If I select and load one of these files, I get a 'Confirmation Needed' window stating that the vessel has the following problem: "<vessel name> is missing part module ModuleDockingNodeNamed" with OK and Cancel buttons. If I hit OK it loads the vessel, and in the Open menu that vessel no longer appears with the Unknown Parts Module error. 

I suspect this is an harmless error message I'm seeing, but I'm hoping someone with more experience and knowledge can validate that for me before I go further.

You suspect correctly.

Thanks for the quick response... you've seen this before?

Only every time I remove a mod that adds partmodules.
It's just a warning, and it's only complaining because some extra part data that the mod added no longer exists. The game will clear out the orphan data when you save the craft, so don't worry about it.
