Okay, so i spotted a guard dog standing on a back porch, while i was messing around (directly east of beacon hill and north west of the docks), I've just started the game for the first time. When i approached it gave me the whole very sharp senses rubbish so i assume there's treasure there. i look around i can't see any treasure, i kill the dog, look around, no treasure, i check online maps, they say that i was right, there is a treasure. I hunt some more, no treasure.
I checked another treasure location with the online map. and that one is also missing, also the almanac page west of the first treasure spot. is this a glitch or am i just not looking hard enough. I've fonund 2 other treasures, but that doesn't explain the almanac pages and these particular treasure sites.
