On two separate occasions playing Multiplayer, the drill has been used to finish off a worm.

The first time it was used just as the timer hit zero. The game hung in between the end of the last person's go and the 'waiting for players' notification. It would have ended the match by drowning both last worms.

The second time it was used it -did- drown both worms (though they were not the last) but as soon as they hit the water and died the game hung once again, not switching to the next player's turn.

The only solution is to Esc - Exit the game.

Will add more posts or edit this one in future regarding issues with weaponry/crashes.

Thanks.
