Sometimes there will be the failure of the dot attribute. If an attribute has not reached the full level, it can be restored by continuing to add points, but if an attribute has reached the full level, it can only be solved by resetting the number of points and re-adding points. There is no law in these cases of attribute failure, I am not sure what operation caused this situation. I usually don't notice anything unusual until I notice that manual production is significantly slower,I was also unable to test the cause of this error, as the intervals between these errors ranged from a few hours to dozens of hours
