Should probably be merged with Flora, IL as the only release zone in it is the city of Flora. This isn't actually a city.
I have merged "South East Illinois" into Flora. There'll now be a release zone in Flora that's also called Flora.
I'm afraid that I can't rename the Flora release zone as something more specific. There are currently no books listed under that zone so there's really no information as to what release spot the original creator of the zone actually intended it to be.
I have merged the duplicates you mentioned. I have also scanned past the 'R's, carried on to the end of the Illinois release zone list and merged some other duplicates that appear later on in the alphabet.
Please let us know if you spot any that I have missed!
