Animated Texture issue

Hi, I am having a strange problem with my animated texture.
Basically the first line of images is read, then the third line, then the second line.
I’m not sure why this is happening, I originally had 35 frames, half of which I deleted (18 left) to see if it would fix the problem (which it didn’t).

The animated maps are generated fine, but the BGE uv image editor seems to muck these up.

Anyone know about this and how to fix it?

Turns out that the texture was being read from bottom to top, something that didn’t show with looping animations. I fixed this problem by re-arranging the frames manually. I might need to try and find a new GIMP plugin that sets up the frames in this “backwards” order. Any suggestions would be appreciated.
