Since the simple traffic configs of the ETK K, FCV, Sunburst, Wendover have been temporarily removed, I saved the old files. Follow the instructions: Unzip the folders Open the Manager User Folder Open 0.33 folder Open the "vehicles" folder Create new folders named "etkc", "sunburst, "vivace", "wendover" Put the unzipped files into the respective folders This will also allow simplified Sunbursts from KLJP to work again. DO NOT PUT THESE FILES INTO THE BEAMNG CONTENT FOLDERS!!!!
I also noticed They said in the 0.33 changelog "due to development constraints", and that they will be added back in next updates. --- Post updated --- The simple traffic configs of ETK K series, FCV, Sunburst and Wendover. If you use simple traffic, these cars won't appear anymore. The devs wrote in the 0.33 changelog that they will be back in next updates. For now, if you want them in the traffic, you can download these folders and follow the instructions.
I think that most people don't know how simple traffic works, so maybe it is a little bit difficult to understand the problem.
do they need to be in a new file, or can they be put in the files that are already there? (if such files are not the "content" folders)
I'm not sure if I really understood what you are asking (if so, I apologize). If you already have such folders (vivace, wendover, etkc, sunburst) in your "vehicles" folder, maybe becuse you have some saved configs there, you have just to put the unzipped files in such folders. You don't need to create new folders. I don't know if I answered your question.
