I find it funny that playing this TSW4 Core release route, in TSW6... still sees floating track and a giant missing water tile on the scenic part of the line near to Lochau-Hoerbranz. How is it not fixed in the 14 minutes between TSW4 and the release of TSW5 or even 6.
In my experience after initial release and a maximum of 1-2 patches dlcs never get touched again by DTG. I don't think players should waste their hopes for more. It's a shame.
I seriously don't get this joint sometimes.. Why couldn't they have continued the scenery to St Margrethen SG which then creates an end to end service for S3+S5! They do it time and time again where they create track but pull the route up short rather than finish it at the expense of further gameplay.... isn't that what they are about "gameplay"! cut the Mastery cr@p out its boring and focus more on finishing the DLCs!
I think it was intended to include St. Margrethen at some point, otherwise they wouldn't have laid the track system there in such detail. But if I recall correctly, there has been some issue with licensing the SBB, so no more Swiss (or at least SBB) content can be done. Not 100% sure on that, but it could be the explanation why the route ends so abruptly, just shy of the Swiss border.
