Know Where to Find Fixes for Fallout 4 Problems
Bethesda has spent years creating Fallout 4 and many of those hours have been spent testing the game for bugs. The developer has probably wiped out a mind-boggling number of problems but you can expect some to slip through the cracks. So, it's good to be prepared.
There are several places that you should have on your radar. One resource is the official Bethesda Forums. We'll almost certainly see bugs and fixes discussed there once the game goes live. The company also has a Help Page that you'll want to take note of.
We also recommend the Fallout 4 Reddit. Users on there are extremely knowledgeable and some (not all) will be willing to help you fix whatever is ailing your game.
GameFAQs forum is another solid place to look for fixes. You'll also want to keep an eye on social media sites like Facebook and Twitter. There are tons of Fallout 4 Facebook groups out there and they might be willing to help you.
If you bought the PC version of Fallout 4, make sure you bookmark the Steam forums. There's already a ton of discussion going on over there.
