Just like with all incompatible test patches - user with incompatible test patch can only join dedis that have same version as him (sometimes higher versions work too, e.g. Z35 client and Z36 server).
Are you sure that the tracks were set to standard config when you tried it?
Granted I've only tried a couple of AS, KY, WE and FE combos, but the AI could join and drive in the standard configs...
Edit: Did you play around with the data/pth folder after you read Scawen's post? If any of those files are missing you'd get the same error message. Since you said WE, KY and AS, and these are the files in the pth folder...
Good suggestion, and yes I'd replaced the .pth files with the files from the smx pack a week or so back while testing out another theory. Checking the file dates reveals that the SMX pack are quite a bit older. That kind of breaks the whole purpose of my experiment based on those files.
Although my AI was pitting correctly during a race, I always ended the race before they entered garages, so I guess those .pth files control that. Edit: and leaving the garages during qualifying of course and why I had the problem now.
Bug?: In mouse clip mode (Ctrl + C), I can still move my mouse to the outside edge of the window. While using a mouse to steer (and using the left click button to accelerate) this can cause the undesired operation of stretching / reducing the window size.
Can you please make it so that the mouse is clipped to the render width and height so that it may not adjust the size of the window while in Mouse Clip Mode.
