@Riashe Good morning. I've just check my code and command 066C as in crash report say. Everything is ok. I think that you have another cleo script for Linerunner/Roadtrain and that cause game crashing. So you must remove one of that script.
Sorry to hear that. It is never happen to any of my cleo mods. I always test them before publishing and I will definitely check them again even they work fine on my computer.
