I was testing a walker with the new system, the one that uses braces, big wheels and unpowered medium wheels, and even if I restart big wheels were going automatically. it happened a couple of other times, even with the other powered wheel
I mean that as I start the simulation, wheels spin. if I stop the simulation and start it again, or reload the machine, or load another machine then load this again, it still does. and I didn't save the file, sorry
