Tiled animation plays strange

[mycats]

Code:

void InitScrambledEgg()
{
    TLN_SetLoadPath("data/scrambledegg");
    TLN_SetRasterCallback(NULL);
    foreground_tilemap = TLN_LoadTilemap("scrambledegg.tmx",NULL);
    background_tilemap = TLN_LoadTilemap("scrambledegg_background.tmx",NULL);
    TLN_SetLayer(LAYER_FOREGROUND,NULL,foreground_tilemap);
    TLN_SetLayer(LAYER_BACKGROUND,NULL,background_tilemap);
    TLN_SetBGColor(0,0,0);
    TLN_SetLayerPosition(LAYER_FOREGROUND,0,HEIGHT*-1);
    TLN_SetLayerPosition(LAYER_BACKGROUND,0,HEIGHT*-1);
    sonic_xpos=65;
    sonic_ypos=193;
    SetSonicSpritePosition();
}

It doesn't happen on versions older than 2.8.0
