Hey! First off, great traits! Love how many new mechanics they introduce.

I've tried the mod with a save I'm still running on 1.5 since I saw it's compatible, and the Observant trait reveals the fogged parts of the map 100% of the time, and more-over it does it on loading a save too. Checked the code and it looks like the check and 25% chance roll that are present in 1.6 haven't been implemented in the 1.5 version.

Also would it be possible to somehow only let it trigger once per map? My reasoning is that even Observant pawns re-entering home maps would not all of a sudden start re-examining everything about them.
Not sure if there's an elegant way to achieve that though.

In any case, thanks to everyone involved for the mod!
