Might be worth checking tier 4 vendors in 1.4 now

Been digging a little in the new patch to see if any of the files have changed, and while Ron's still got the same bug as before (has to be assigned to a trading emporium to unlock full items) and Holt doesn't have any settlement options still, but Smiling Larry does now.

I'm going to guess moving them somewhere won't work, but at the very least for console players this means you could intimidate him from in front of Med-Tek to Greentop Nursery and get Reckoning that way. I'll keep digging and see if any other changes are abound with the files, but that's one that'll probably need checking the soonest.
