With beta14, on the track selection page I cannot see the track "image" for some tracks (but the track loads fine):

The problem seems to be related to the number of tracks: up to a certain number of tracks, all tracks have their image correctly shown. Above that number, the tracks at the end of the list will not have the image (while the ones at the top will).
Example: 121 mod tracks (+ Victoria), the last 3 track sin the list I can't see the image (Victoria is 2nd last, no image).
If I take away 2 tracks, all works fine.
I doesn't matter if the tracks are under the gpb folder, under the "mods" folder or split between the two.
