WTF in CS:S

[leDoOd]

I was minding my own business, surfing around in the CS:S map 10x_final. All of a sudden, I looked down and saw that my *ahem* nades were following me, and every other person in the map had slow nades as well.

By far the strangest bug I've ever seen in this game, especially since my ping was 30.
