Hello Marcin!

This was patched in this @stiangre commit:
https://github.com/FreeCol/freecol/commit/fe0931d2e818925e6aada93ccc69832d446dcf92

As a note, the error occurred if "seasoned scout" is not selected as test unit

I've tested it and it works on the current production branch.

Thanks for reporting!
Bernat
