Worms that emerge from the ground stop movement before visible.

This happens with other things that appear as well, but the worms seem to be a more flagrant offender. Often I'll be stuck on something, which in itself is extremely frustrating when movement is so critical to the game, then the monster will pop out of the ground.

I've gotten used to this, so I know whats happening... nearly instantly, but the server is registering the presence of the monster before its on my screen.
