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.
