The image values in SectType.txt are off by one. They start at 0, not at 1. Look at the first entry in stock se4:

Physical Type := Planet
Picture Num := 0
Description := Huge planet with an abundance of surface minerals.
Planet Size := Huge
Planet Physical Type := Gas Giant
Planet Atmosphere := Carbon Dioxide

This uses the first picture in the list, which is p0001.BMP. But, the data file is read with a decrement of 1, so this image is called by

Picture Num := 0

and not

Picture Num := 1

So, to get the picture used by an entry in SectType.txt, add 1. There is nothing wrong with that warp point entry. That warp point you posted actually uses the image p0296.BMP, not p0295.BMP.

The problem is most likely that you are trying to load a game created with a different SectType.txt file than is currently used, which will cause such problems to occur. You CAN NOT change the number of entries in the SectType.txt file and expect any current savegames to work properly.
