To preface: I am referring to the Scout Extra_D Standard. (Trucks will not encounter this issue)
What's Happening: The car will not exceed 47 km/h (not MPH), and right after it reaches that speed, it will slowly decline to around 30 km/h, and no amount of acceleration will help. This is both within city limits and on the highway. I am in Europe 2, which is an unregulated server for car speed, or cars in general.
What I've tried:
I tried shutting off the speed limiter in-game (which should be 90 km/h, but nonetheless, I tried). It actually will not shut off, when I untick the box, it will simply retick itself. (This issue is non-existent when I use a truck)
I tried shutting off the speed limiter in the TruckersMP setting. This was already off and won't turn back on without my conscious decision.
I tried selling my old Scout car and buying a new one. Nothing changed.
Not sure what else to say. This is a very strange glitch. If you need any follow-up information to address my problem, I'm ready to provide. Thank you so much in advance.
