Workaround when linking vak tot another and removing that?

[luttje]

I removed a VAK, which caused this error:

Perhaps the VAK had a link? I made a quick workaround with: e172070

However this will likely break expected behaviour around linking. I don't have time to investigate further atm. Help wanted
