Some of your TerHills construction roads are constructions for artificial lakes, as seen in the sadly slow-loading park map: https://photos.centerparcs.com/user/plan/NL/TH.pdf
I'm not planning on starting an editing war. Are you fine with keeping an eye on those construction roads of yours for further change? :)
Lastly, the PDOK satellite view has slightly more recent images than AIV Flanders in this case, so it might be useful to compare both satellite views for your sources. :)
