Hawaiian Shirt Anomaly 

Although a rational man such as Phill is unlikely to fall for superstitions, his dedication to BL5 and the effort that he has put into improving it might cause an anomaly to occur. This anomaly might cause unreasonable amount of downtimes and seemingly impossible situations where there can only be one possible reason... Someone has the Hawaiian shirt on.

Line actually breaks down and Carlos learns the lesson of the Hawaiian Shirt Anomaly.
