Aircraft shadows, which followed the aircraft smoothly in an executable from the 25th, now move in a stuttering and jumping fashion. It looks like the shadows moves in increments of whole tiles, because the shadow jumps from side to side when the airplane flies diagonally with respect to the tile grid. I don't think this is intentional, because it looks ugly.
I built the executable, makeobj and pak64 today. Windows, 32-bit simutrans.
thanks for reporting, should be fixed in r4898.
Looks better now. Thanks.
