Circumstance: attempting to throw an object, path of thrown object goes over a square with Deep Water (~).
Bug: path is resolved as if trying to throw through impassible terrain. (“From the East, you hear Thud,” thrown weapon is deposited on the square along its path immediately before it would have passed over the Deep Water.)
Notes:
Tested with a rock and throwing knife, both against a monster and against an empty square.
Throwing over Shallow Water (~) works fine.
Shooting a firearm or launcher over Deep Water works fine. (Tested with G36 rifle, finger laser, M203 launcher)
