Commercial coverage D losses in the UK from the Europe ETC model do not get generated when damage is very high.

Issue ID	286
Summary	Commercial coverage D losses in the UK from the Europe ETC model do not get generated when damage is very high.
Description	In the 2019 release of Touchstone, the Europe ETC model was updated to also contain the GB Surge model as part of it. The resulting losses for the Great Britain region thus now include both the ETC component and the surge component, for applicable events. In some cases, however, coverage D losses do not get produced when the no. of Business Interruption days crosses 516. Instances of such a high BI downtime days value are extremely rare. This occurs only when running both wind and surge together, for commercial exposures in the Great Britain region.
