Hi,

I only added the tags to upgrade the regular De Lijn Bus Routes to De Lijn by adding the network tags and/or wikidata tags. There are some warnings lefts for MIVB/STIB routes. 

I did this in preparation for swapping the roundabouts by a crossing around the church in Vilvoorde which I plan to do in JOSM.

Caused this any corruption in the data? I want to avoid that as much as possible now and when swapping the roundabouts.
