Ive found that the map hasn't updated on Niddertalbahn and still has its original map that came with TSW4 and not the new TSW5 one, with no labels, train info or hop points.
TSG have used their own map assets (grey instead of blue tinted background) for NID. Likely the map is not using the core assets, hence it's not affected by the core update. DTG Lukas Maik Goltz I think this would need to be updated?
