I've seen this happen several times. The larger/stiffer the wire, the more likely to be an issue.
We also have had many instances of a crimp tool deforming the connector so that it pushes down too much on the spring clip in the connector housing. When the other mating connector also has a bent crimp or torqued wire, it is likely you'll have intermittent electrical contact.
