So, having calculated drift, basically there are two problems:

1. the map is shifted in a couple of pieces:
* japan tried to collide with korea
* the americas are shifted one direction
* the lakes inside north america are shifted in a slightly different direction
* most islands near the south pole seem to be shifted
* australia and pacific islands seem to be shifted in another direction
* lakes inside africa are shifted in a direction
* some "lakes" in africa are mostly phantoms
* the caspian and aral seas are shifted as a group (the aral sea is also too big)

We're working on retouching the map to address most of the above. With the replacement, we will only need to correct a smaller number of points.

2. everything else
* various cities are totally misplaced
 - caracas, venezuela is in Italy
 - baltimore is in the deep south
 - acre, (western) brazil is in the middle of a run of cities in central brazil
 - aragaju, (eastern, coastal) brazil is in the same run
 - montserrat an island in the gulf of mexico is in the pacific ocean
 - augusta, maine (near canada) is just north of florida
 - sana, yemen is in oman (nearly at sanala)

-------
* various time zones are confused
 - victoria seychelles has the time zone for melbourne, victoria, australia
 - phoenix islands (pacific) have the time zone for phoenix, arizona

-------
* some cities need to be added / removed to make the map sane
 - add anchorage, alaska to fix alaska
 - remove guam, usa
 - add Longyearbyen, Svalbard to fix north of the nordic countries
 - remove saipan, n mariana islands

* some cities could be added to help the map:
 - la paz, mexico

-------
* the time zone stripes are generally in the wrong place
 - chihuahua and mexico city are in the same stripe but different time zones
 - jordan and cairo are in the same time zone but different stripes
 - sudan is in the same stripe as cairo but a different time zone
 - time zone stripes for russia near alaska and alaska near russia are wrong

there are a couple of cities/countries whose names are probably wrong, but that's really a localization issue and i don't want to spend the time explaining any of that to people.
