I participated in the fallout 4 beta patch, however there no longer seems an option to turn off Beta and I haven't seen / received a new update for fallout 4 version 1.2 (I restarted steam to be safe, but nothing). Is this because I'm still seen as being in the beta version? I'm sorta confused if I have 1.2 or not, but dont know how to check my version in game.

I'd like to point out that no one is going to be able to read that, unless they highlight the text, so maybe for convienience sake change the colour back to white?

The last beta patch became the 1.2 patch, the reason it didn't opt you out after the patch went live it a quirk with steam, if the version in-game reads as 1.2.37.0.0, then you are fine.

As stated, it's a very, very minor issue with Steam simply not removing the [Beta] tag.

It won't effect the game in anyway. the reason you didn't receive the new update when it went live was because you already had it.

Check menu - settings. Version number is shown, bottom right. Should read 1.2.37.0.0
