Subject: Flip timed effects
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=55bfc8115a311dd080d5648743070885562a362a;p=nethack

Flip timed effects

In wizard mode, freezing some water on the ground, then
flipping the level did not flip the coordinate of the ice
thawing timed effect. This could cause an impossible complaint.
