Steely_Gaze: Huh, this is weird, because for some reason I'm not having any issues at all.
I purchased as a pre-order a week before it arrived (thanks to the late release), downloaded without Galaxy, am running Win 7 64bit, Core i7, Nvidia GTX 760, 8gb of RAM...
I have the same specs as you have, instead of only one difference: The CPU. Mine is a Core2Duo-CPU
which keeps me thinking if the water bug might be CPU-related. Anyway just speculating...
BTW: I got my hands on the Steam version and it doesn't crash at all, but in the Steam forums people
have already reported other bugs as well. So i will take a
VERY CLOSE look at what Team17 has been fixing
in the patch that hopefully will arrive on Monday.
