While doing the brotherhood side of this quest, whenever I put the fusion charge on the reactor I'm meant to get teleported to proctor Ingram but instead get double teleported back outside the CIT ruins where liberty prime breached the institute so I can't finish the quest. I'm on ps4 so I can't even use console commands

After starting this quest, >>>do not enter the institute in power armor<<<. it can turn NPCs hostile for no reason, skip over quest stages or bug the whole thing so you end up in the institute alone with no objectives and no way out.

this article is hilarious in how wrong it is every faction (excludeing the institute of course) has this as an ending so whether you went minutemen railroad or bos you're good to get this
