I have gotten all 11 but only have 10 actual chests in my list that is why I say meteor might be one.

Thanks!

I'm down to just 1 secret left. I think I'm going to have to backtrack through the game to find it...

This is a good lesson for me to make better notes next time...

I made obsessive notes the second play.
Now on my third play I can move around in the maps in my head and see where I found secrets.
I have been playing too much for too long... or maybe that is just fine!

if you still need help after backtracking let me know.

Found the last secret It was one I discovered in my first play-through but had forgotten about, so I don't feel too bad looking it up

Ahhh... thanks all for your help.

Can you please share your last secret?

I`m too 76/77 , I checked all the maps and I have no idea what could be missing

Sure!

Got it finally too
I was missing to solve 4 plague puzzle - No idea why I skip it, but I had full map so that was the reason I could not "find" it
