Hi, we bought a 2 second 3 man tent last week to go campin gnext weekend (hopefully). In all the pictures we have seen the tent has the built in guide rope at the back (from the ventilation flap), one either side and two at the front. However, ours only came with one for the front. Is this an omission or is only oen supplied? Odd if it is because the pictures show two including Decathlon's own videos. It's a bit of a pain because we don't live near a store and Decathlon don't seem to have email contact addresses.
