For the Don't Look Down Challenge Puzzle, if what you get doesn't work note that the -16 (5th from the end, after the +9) should be a -17.
In http://www.AncientSocieties.com/convo/ in the 6th line, the last symbol should be Olmec (gold)
In http://www.AncientSocieties.com/echo-chamber/ if you matched up the words the most obvious way, where the lengths and patterns matched, the result was missing a letter "R". (You could get the missing "R" by swapping two of the words and matching them up with words of a different length, but then by that logic, any word could be matched up with any other word, resulting in a lot more possible combinations.)
In http://Endgame-ARG.Wikia.com/wiki/Pressure the third letter of the theme keyword "escape" was spelled "esdape", so that you were thrown way off if you recognized the presence of the theme word right away. (This is where I first realized they're purposely trying to avoid making it too easy.)
In http://www.AncientSocieties.com/anthropology/ the "Still Waters" clue implied antipodes, but instead you have to use the Longitude values that are an equal distance from the Prime Meridian in the opposite direction (the negated value).
I don't think we ever determined what the intended path to solve http://www.AncientSocieties.com/again/ was, but based on using the same technique throughout each line, you'd think each line in the last group would be the same as the corresponding lines in the first group, with "255 217 0" appended to each line, so maybe the middle part of the last line should have been "0 85 168" rather than "236 0 0". (The answer "camouflage" was found via Saturday's challenge and "camo" via back solving.)
In http://www.AncientSocieties.com/crib/ some of the paint stripes on the caboose probably do not end where they should.
In http://Endgame-ARG.Wikia.com/wiki/Dam_Tour you originally counted all the circles and digits. The lines had 14, 23, 26, 34 and 40 symbols but since those should have been double the number of characters in the answers, which were 7, 10, 13, 17 and 20, the second line was wrong. When the image was updated to fix the second line, it was also changed such that you would count the two-digit numbers as one rather than as two separate digits.
In http://Endgame-ARG.Wikia.com/wiki/Blueprint the second line 127.313 + 323.992 adds up to 451.305 but the result should be 415.305 instead (was later fixed)
In http://www.AncientSocieties.com/unboxing/ the A:HRN should be A:HRH. Was the H changed to N so that the letters would include an anagram of HINT WATER?
In http://www.AncientSocieties.com/privacy-window/ you had to use the misspelled version of "straitjacket" (as two words, "Straight Jacket") to get the last character "H".
This one appeared to be unintended, since "stl.la/straightjacket" did not work.
In http://www.AncientSocieties.com/fireplace/ the colors should have continued with: Yellow Red Orange Blue Yellow Blue Purple Red
In http://www.AncientSocieties.com/in-circles/ the text clue suggests reading down the columns first, but instead you have to go in normal reading order for Americans and Europeans, left to right then top to bottom.
In http://www.AncientSocieties.com/gaff/ the fourth line of the last group should read d) (7.5,3.5) -> (4.5,3.5) F.
In http://Endgame-ARG.Wikia.com/wiki/Wall_of_Fame the text for the last picture eliminates all of the letters. Instead of "-Six each muscle", it should be "-Musicals exec".
In http://Endgame-ARG.Wikia.com/wiki/PIllows?oldid=7092, the first "+" should be "-" (hence the reason for the nested parentheses), making it "[AcCUSe - (-HIS + SICKNeSS)]84+53+16+8+7 - 53+8+7+16". And on the solution page, the math was wrong:
AcCUSe = 89 + 6 + 92 + 34 = 221
HIS = 1 + 53 + 16 = 81 - should be 70
SiCKNeSS = 14 + 6 + 19 + 10 + 16 + 16 = 70 - should be 81
In http://www.AncientSocieties.com/whats-in-the-box/ you had to encode the cipher text rather than decode it.
In http://www.AncientSocieties.com/bulletin-board/, the white patch in the middle should be either STS-45 or STS-57, not STS-11, which made it hard to find the first letter of the solution (fixed later). The resolution of the image was also changed from 1500x1023 to 2500x1706 so you can read the Soyuz 16 patch.
In http://www.AncientSocieties.com/a-terrible-thing/ the first circle in the second line works better if you assume it is red rather than brown. That part gives you the number of steps and methods needed to decode the puzzle and as is, it appears that one of the steps is a "no-op" rather than indicating the actual manipulation needed for that step.
In http://www.AncientSocieties.com/lugdunum/ if you put the point of the pin where indicated, you get an "H" where you're supposed to have a "G". You have to place the pin a good bit lower to get the "G".
In http://www.AncientSocieties.com/two-hundred/ the words in the bottom of the last two columns, presumably OTHER and SIPHONED, should have started with IT and SY respectively.
In http://www.AncientSocieties.com/dont-look-down/ the value "31" represents an "S". Using the resulting word, you have to make three "leaps" to get to an answer that works. For the first "leap", you can do a Google Search which provides the correct spelling. For the second "leap", you have to find a specific one (Arles's) which sometimes has a slightly different spelling and fits with the theme for the week, which is names of specific tunnels. For third "leap", to get the actual solution, you have to drop the "Arles" part.
