How come sometimes when I rope and drop a dynamite or mine or anything, it automatically unropes me an does not allow me to get away with a 3 or 5 second retreat time?

A second bug was also in the first Worms XBLA game.

When there are a mine, a worm, and some water. If you rope to the mine to set it off, and the worm falls into the water (dieing), it will automatically detach the roper, even when you have done nothing yourself, like dropping a weapon.
