OK, I just fixed a bug that might be a little confusing, so I wanted to explain.
Since the expansion, there was some problems with cases that should have either featured Larry the Toe, or that one of the political groups was interested in. Bascially, you were getting political interest from the Delhi factions, regardless of what city you were in and Larry was never showing up (he should only show up in New York, btw).
Both bugs are now fixed. I'm sorry if it interfered with anybody's ability to finish a treasure hunt, but I can't really go back and try to make up for that now, so we'll just have to chalk it up to bad luck.
