Thank you @chard1484 for reporting this. Would you mind trying the latest build?

https://github.com/njthomson/SrvSurvey/releases/tag/1.1.3.120

[njthomson]

The nature of this failure is due to incomplete data about the system. I've seen things like this previously when the quality of data downloaded from EDSM/Spansh was weird.

@chard1484 - what system were you in at the time? Had you DSS'd the whole system yourself?

[njthomson]

This should be fixed in build .123: https://github.com/njthomson/SrvSurvey/releases/

@chard1484 - please let me know if this happens again.
