All those addface errors are from object bender and don't actually effect the route. Make sure y'all are putting your objects into Railway\Object. A lot of people have been putting objects in the wrong folder with this route for some reason. Make sure you have the 6, LisaRaye2 and the Culver pack installed before you install the 5. When you install the 5 make sure to overwrite objects when asked.
Trust me I've never had any issues with objects missing or anything before and it's been like a lot of years (like 10+) Even before making a post here I double checked everything. Copied things over even though I put everything where it should be. I even dragged the folders one by one in corresponding places from the 5 train .RAR file and there is no overlap of folders or anything. My parent folders are organizing the child folders nicely and as should. Ie. Railway>Object>LisaRaye2
Every object folder is in the object folder, sound folders in sound and so on.
Even the 6 train route I have is perfectly fine without missing station roofs or anything. So I am stumped. Have you checked if maybe the .rar is fine?
Update 2: Guys having this issue, somehow an object folder here has "modified 2011" files that I overwrote without thinking/looking and the ones I had were "modified 2013". I restored my 2013 ones from a backup and it fixed some of of the issues in this 5 route (but not all, still a bunch of things missing). So maybe it's the same for ya.
