Browsing through the default data file, I noticed that (very rarely) a textList can have a 'unique' attribute. For example, the BOARDERS_TEXT textList. This attribute isn't documented anywhere that I can see, so I wonder if anyone here knows anything about it?
Does a unique=true textList mean that each option can only be chosen once per sector? (like a unique event?) Seems a weird way to do it, because...
1. If the event that loads the textList isn't also unique, then you could 'run out' of textList options (if the event occurs 1 more time than there are options)?
2. OR if the event IS unique, then what is the point of making the textList unique too?
But I'm not sure what else it could mean.
Also, I wonder if textLists are always unique by default? I only can find the attribute used when it's being set to false, so I would assume that means you need to explicitly declare it NOT unique (otherwise it would be). However that would seem to make the odds of "running out" of options (as mentioned above) quite high!
If anyone has any info or even guesses about the unique property for a text list, please don't hesitate to share. If we can figure out how it works I would be happy to update the modding wiki too

Thank you!
