If you would be so kind, please patch Challenge 13. Possibly the buggiest challenge of them all...which really makes it one of the hardest challenges. I've wasted a lot of time trying to get past it only to have the clock freeze during sudden death. Another time I was nicely entrenched at the absolute top of the map when suddenly the last enemy worm teleports off the map above me...past the SOLID inpenetrable part. It's slightly annoying to drown at the very top of the map with a solid half an hour down the drain...especially when the CPU is CHEATING.

Kthx. ;)

This is covered in other threads. It's being investigated.
