Looks like Sunday morning is a good time to spot glaring mistakes on CNN/I!
At 1039 gmt, the rerun of World Sport came out of a break. However, instead of World Sport, we came right in the middle of a weather report from Martyn Jeanes. This was followed by Shihab Rattansi ending World News! This was the end of this morning's 0800 to 0830 gmt edition of World News, somehow being rebroadcast!
When World News ended, again(!), World Sport continued abruptly, in progress.
