3.5 UA 'environment' Half-Orc/Half-Elf racial subtypes don't work

[loubranch]

Poking around in the latest version of PCGen - 6.09.07, the hyphenated-name races' environmental (Arctic, Desert, Jungle) subraces don't work. Environmental race subtypes with non-hyphenated names such as Elf, Kobold, and Dwarf function normally. These are defined in Unearthed Arcana (UA) inside ua_abilities_race.lst.

I think the issue might be the TYPE (eg: TYPE:Half-OrcSubrace.AltSubraceChoice) when looking at the selector within the pcgen UI - An example of one that appears in the subrace selector (frostblood) shows TYPE:HalfOrcSubrace. However, tweaking these values into a homebrew .lst file doesn't seem to solve the issue.

To reproduce, create a new character in the 3.5 ruleset including Unearthed Arcana (Complete), select race 'Elf' and go to Race Traits, assign a Race Base. All the subrace options will appear. Change Race to Half-orc, go to Race traits, assign the proper race base, and few or no subrace options appear.
