Adds a fog gap for the CLF LV Nightmare Insert

Explain why it's good for the game

The CLF on LV having their ship spawn on the North side of the river and not getting RNG Jesus'd by having a fog gap nightmare insert spawn in, are basically doomed because they cannot hold their ship since it's too large and they can't hold anywhere outside it because it's wide open ground easy for xeno pickings. So giving them a small fog gap which in my opinion by the time the marines deploy will either not be noticed due to the fog dropping in general or be a gap for 3-4 minutes if they land early. I feel like this is a lakehouse situation but with the fog making it virtually impossible for the CLF to have a game unless the xenos let them survive, which to give them some credit they have done so. Not to mention that the insert is very rare so the gameplay balance side of it will not be so unbalanced towards one side. It is just giving the survs a chance and increasing their survivability from zero (I better not hear the usual "But surv is meant to be hard deal with it skill issue" If that's the case might aswell remove the insert like the lakehouse one.)
