rustyr: i loaded the new game + with hearts of stone too to start a new game and the ground even in buildings is water. makes great for indoor pools but not for a game . would appreciate any help.
It might be an Easter Egg. In Thailand and other Southeast Asian countries, they celebrate the New Year with a Water Festival (called "Songkran" in Thailand), where people splash water everywhere and such. So just like around Ghristmas you might see Geralt wearing a red Xmas cap or such (a Christmas Easter Egg), now you see water everywhere.
There seems to be a bug with that Easter Egg though as the Water Festival is in the New Year of the Buddhist/Hindu solar calendar, not the Gregorian Calendar. So the Easter Egg shouldn't actually be triggered until April the 13th or so, when the Water Festival actually takes place.
Understandable mistake, but still.
