This isn't a typo so much as the text being too long to appear. It presents a scrollbar, but clicking it does nothing.
Outro of the 3rd adv in Shrine of the Astral Guardians: "...Despite your best efforts, which include shouting the word friend repeatedly in obscure languages, you are unable to solve it this riddle...." Suggest: ...shouting the word 'friend'... Typo: ...are unable to solve this riddle...
Outro of the 3rd adv in Riddle of the Gnome Lords: "You have scoured the Gnome Hall for source of the corruption..." I'm no english expert...should it be '..Gnome Hall for the source of corruption' ? Checked against Google search 'source of corruption' and 'source of the corruption'. Maybe Sir Knight can comment on this.
I know it has been mentioned before, possibly several times, but I didn't see it in this thread so I'll post it here for completeness. The text shown on the character sheet when you have no item equipped in the class skill slot is "Martial Skill", "Arcane Skill" or "Unskilled Divine". It looks like "Unskilled Divine" should be changed to "Divine Skill".
Beneath The Frozen Earth Under the picture "High in the [...], the Trog wizards plot[s] to devour [...]" I think it's only one wizard (the King) or not?
Wizard's Workshop module, 4th battle. Battle description states three Ornithopters when there are actually only two (was change in 2.15).
In The lvl 14 optional adventure, Lord Bartford's Manor, The opening text *Which I'm unable to get up as I clicked through it and even fully restarting the adventure is not bringing it up... bug?* Seems like it should be Karen - Gary - Karen, instead it is Karen - Karen - Karen. The dialogue is roughly 'hey Gary you look pretty tired, mind if I take over?' then Karen says something again. It could be insinuating that at this point Gary has passed out, but I'm unsure.
Lvl 16 Adventure 'Attack of the War Monkeys' Karen states 'Wo you have an observatory?' Perhaps she means 'Whoa'?
Module text before 4th stage of the Black Forest adventure (post-War Monkeys battle), "...the trees become more animate..." might mean animate (a-ni-mutt), but I think reads better as "animated." Is that the intention?
Aftermath text for stage 1 of "Attack of the War Monkeys" says "...the plight Cardhuntria," missing an "of."
