I double-click to pick stuff up...I've lost so many good items doing that from just my vault. Someone needs to fix that. It doesn't register that I've picked the item up but puts it in my inventory...and then when I Nexus again the thing is gone.
When battling the SAW guy, use the Eagle Eye perk and have a sawn-off shotgun - condenses all of that bullet spread damage into one strong little bullet. + if it helps.
We really need a /solo command or something, stops people teleporting to you or coming near you. I'm getting tired of random people teleporting to me and following me in godlands (although it's funny when they die...).
