We recently took a look at the Fallout 4 port ourselves and while Bethesda has done a pretty decent job with the game, there are some notable bugs and issues with performance that could use some work. If you do plan on using the console in Fallout 4 at all, then you could easily protect your save files by backing them up, this way you can always revert to a non-corrupt file if something does go wrong. One person chimed in to claim that he has been using the console in most Bethesda games without issue, to which Hines admitted that not everyone will have issues. Answering a fan question on Twitter, Bethesda’s Pete Hines explained that the use of console is “not supported or recommended on PC”, he then went on to say that it can “very easily mess up save games”.
With a game as big as Fallout 4, losing your save file could result in hours worth of time lost. However, with Fallout 4, it seems that Bethesda wants to warn against it, as it could “easily” corrupt save files.
It is common for PC gamers to use the developer command console within Bethesda games to access certain things, like secret rooms filled with every item in the game, or cheat a little by unlocking a door or adding a few extra experience points to your character.
