BF2S Forums Missile silos not firing in the demo sometimes?

This happened to me maybe three times out of the ~20 rounds I've played so far. Missiles just not firing for more than 5 minutes at a time. Meanwhile the 2 sides are fighting for control but with no result. I'm assuming this was a bug, but was it something else? I've always just left the server whenever it's happened. Anyone else getting this sometime or have ideas?
