The PC section has a Bug report topic: http://www.gamesas.com/topic/1544248-bug-report-index-pc/
Not sure about the Xbox or PS4 forums.
I don't know of an official place...maybe they are keeping track when people contact Bethesda directly about bug issues...
But if you would like to discuss your particular issues on here, try this...http://www.gamesas.com/forum/316-fallout-4-hardware-software-issues/
I think the "let the modders fix it" mentality is OK (at least it shows BGS is cool with modding), but they've left too much/too many unfinished/broken things in this title.
Only if they over-rely on it (which I think they did, this time).
For the record, I'm part of that console crowd (XB1).
