Just ran through The Jelly Farm 2, and activated the first turret. It lasted throughout the whole battle. After the first battle I brought some enemies in from the next room, but a Lumber was able to kill the turret (I was kiting around them and I got behind the turret). Are the turrets supposed to be able to be destroyed? The wiki says they shouldn't. Were the turrets changed when they were reintroduced in Jelly Farm 2? Or is it a bug?
