Pathfinder typos where "s" appears as a word by itself and s/b with a leading apostrphe or where it s/b a "5" or where a word is split when it shouldn't be, such as "benef its".
I found several of these including:
Pathfinder Player Companion: Quests & Campaigns
several " s" should be "'s", and feat Expert Trainer: "s days" s/b "5 days"
feat Foeslayer "benef its" s/b "benefits".
I then did a text search accross all the data and found more. I'm fixing them now.
