My idea seems to work well and shows no issues if I parse out the UWP data into those individual fields for entry into the db.xml. I am no longer entering any data into the <uwp /> db.xml tag.

Ironically, I found that there are some conflicts between abbreviations for Bases in the ruleset vs what is on Travellermap. I will submit a bug post about it.

I will get an updated version of my extension submitted. Thanks.
