Stop Robot does not stop the robot if there is a loop inside

Stop Robot does not stop the robot if there is a loop inside, let's say using while or for

Remove instance removes the instance but i can clearly see that the CPU is still loaded with that instance, the only way to remove the instance in this cases is to Build the robot again, only after that the CPU load of the previous instance is removed.

Everything is fine if i try to Stop Robot after the loop is finished

Any advices on how to stop the instances when some loop is still running without having to remove instances and rebuilding?
