speaking of game bugs - I guess it's fine posting here instead of making a new thread.
Pretty sure this is well known by most of you, but it just happened to me for the first time while watching a game replay.
Once I pressed R to restart the replay, somehow it loaded a random shopper-like map and the gameplay was being all fake - I mean, the worms weren't acting as they were supposed to.
Also, you can notice some kind of bazooka with homing powers, note the pointer
It seemed weird but fun too. It happened in a replay afterall..
