In my opinion, the issue with the current TS scenario editor is that it's all over the place. You need to fill weird graphic interfaces, you cannot go straight to a train station on the map, instead you need to travel with arrows keys on the route and easily get lost in the middle of nowhere (please let me know if there is another way to travel quickly to a train station, I followed many tutorials but they all use this painful way).... Also, when my QD scenarios finally dare to show up in RWE2, they're unusable as there's no train stations to select. Such a mess....
BTW, my created standard scenarios won't work in RWE2, I tried everything, either they don't show up in RWE2, either they crash when I start from TS....
