There are some errors with rivers. I'm not going to go into precisely which path they follow, but rather I've spotted some that do not reach the sea, or have no mouth.
Don River

This river does not meet the Sea of Azov, but ends (near the base of the A in TANA) a short distance from it with its last bit pointing in the wrong direction.
Another river is supposed to be its tributary, but instead ends near the large S.
Volga River

Does not meet the Caspian Sea but instead ends in the middle of nowhere.
I reported this in the Demo Bug Reports thread.
Danube River

These are "distributaries" and should have their mouths at the Black Sea rather than the Danube.
Blue Nile

This river should reach the Nile, to the north-west, rather than having no mouth at all.
A river in Southern Russia

I've drawn some arrows on here. The heads of the arrows are the mouths of the rivers.
You should be able to see this is somewhat odd. Obviously, this river should have its mouth at the Black Sea and the rest of the tributaries reaching it, rather than stopping short.
Those are all the errors I have found so far.
