We were on a caravan from the Fortress to the Hub and we were ambushed. I exited through the grid and expected my companion (Francis Reed, S.P.E.C.I.A.L. - 8 8 7 6 10 10 10, level 10-11, SG 155% ) to follow me, but I guess he died.
I told him beforehand to meet me up at one of my tents, but after this encounter, I couldn't find him at my nearest safehouse.
I checked my party points and the game said it was 100/150 at the time.
So, I started to systematically check all of my safehouses, but after I looked for him at 2 or three of them, I checked my party points again only to find out he's been vanished.
"Party points used: 0/150"
He was a really badass companion and I really want him to join back, so we can head out to the wastes once more to pulpify some mutants and take some names.
edit: Oh, yeah.. he had maximum loyalty at the time he dissappeared.
