My installation is quite large with many items brought over from Rail Simulator but I do not have many modified files and re-skins. It is mainly straightforward content. Most of my mucking around is with routes and scenery assets but I have been route building in RW2 and giving it a good test and not one SBHH. This is also on two installations of the program.Geoff just out of curiosity, you say you have had not a single ounce of trouble with RW2, do you mind me asking how heavily modded (or not) your RW install was prior to the update? By that I mean did you have hundreds of re-skins etc installed and various community mods to sounds/physics etc??
I would say that I generally stick to proven methods and third party add-ons.
