Since I've been digging in the files while modding, I've been keeping some notes on errors (mostly just typos) as I notice them (but not all of them, because I'm not that organised >_>). Aside from some more general notes, I'll list the exact passage names for ease of fixing:
-- General --
The prices of items don't take into account charges. For example, it only costs 0.75 gold (the price of 1 donut) to buy the box of 6 donuts. Same with cake, the giant fruits, etc.
Store vendors always say their thanks line, even when buying items, which doesn't really make much sense in the case of the Earl's/the racoon's.
Some of the not-formatted-for-players'-eyes passage names can be seen because the game always displays the passage name beneath time. One example are the vendor parts of the stores.
-- bubble orca ai --
"waves with her tail as you drift away" should be "waves with $npc1.his tail as you drift away"
-- cabal dragon ai --
"he lets out an stifled, beast-like growl!" should have "a stifled"
"The tendril ceases" should be "The tendrils cease"(?)
"looks immensely please" should be "looks immensely pleased"
-- Slay Queen --
"that as inside the queen" should be "that was inside the queen"
-- thin fur ai --
"the $npc1.species is send sprawling" should be "the $npc1.species is sent sprawling"
-- A near bursting patient --
"says betwee groans" should be "says between groans"
-- spell objects --
In `$lighning3`: "chant an invokation" should be "chant an invocation"
