(svn r7631) -Fix (r1): some pointer arithmetic gave the number of entries instead of the number of bytes to move when removing the animated state from a tile. This caused desyncs between Little and Big Endian machines. Thanks to pv2b for helping me in locating the bug and to Darkvater for figuring out that the arithmetic returned the number of entries instead of bytes.
