What would really be useful is a list of all the buggy / non working achievements so people don't waste time chasing the impossible.
"The Paul Murphy Award for Excellence and Attractiveness" log doesn't seem to keep track of civolopedia entries read.
"Tomb Raider" Many times taking over the Egyptians never seems to work.
"The Elephant Battle" Tried this against different UU never seems to work.
"War Canoe Attack" Not sure if I've tried this yet or not myself but have read many have and no joy.
"Cat Fight"Tried this many times never unlocks.
"I Have the Power" Have had many units win 20 fights never unlocked.
"Hundred Years War" Another I haven't tried personally but there doesn't seem to be a counter in the log for this.
"Can't We All Just Get Along?"I've done a few games with no wars and never unlocked.
"Magellan" Semi bugged have to edit xml file to get to unlock.
"Knowledge Is Good" haven't tried reports of broken.
"Diplomat" Ditto
"Manifest Destiny" tried to get this one a few times never seems to work.
"Model of a Modern Major-General"Lancers and lancer replacement UU don't seem to register on the log
Think I got them all that are bugged
Oh should also say alot of the attack ones B-17,I can has nukes etc might seems bugged but I found that you can't open the war with the attack and get it too unlock I had to declare war wait a turn then use the nuke b-17 etc for it to register.
