I do have a few Organized colonists. Thing is, the game never actually tells you. There's no message or alert about it.
You should check this event also why the gui alert doesn't appear...at least i don't recall seeing the message sent to the odinRenderer that is defined in the event script...maybe target citizen is not properly initialized ?
I am on the experimental with both files replaced, my naturalist still isn't being supplied. I started a new game after replacing the files, am I missing something?
