(Pardon me for my spellings) In Altis geographical lore, "there are 3 periodically flooded flats on the East side of the island: Almyra, Limni, and Ochrimlimni," and "in the summer the Almyra flat serves as an auxiliary landing strip." This is true both in summer and in winter, also in all seasonal times in between. This should not be the case.
There should be flooding occurring in these flats according to the lore, and perhaps another engine feature: flowing water.
Currently, the oceans just sit there. There are no tides, no liveliness to the water. It's just... There.
