I figured it out. It appears to be a problem with the entries in the eastkarana_chr.txt file. I can add additional character models to it, and it works fine until I modify a quest in the zone. Then it seems to become corrupted and it turns everything white. I deleted all but the first entry and now the zone is back to normal (except of course for the NPCs that bear the character model IDs that I deleted--which are all the interesting ones). I guess this will be a question for the Windows Server forum.
