So i've been playing fine for a while mainly doing side quests and exploring, i spoke to a travelling trader who told me about vault 81 didn't bother with it until yesterday but when i went there i couldn't open the vault i use the pipboy hit the button but nothing happens after attempting to open the vault my V.A.T.S stopped working completely too (i had an earlier save to reload to and confirmed it was the vault that broke my V.A.T.S) i thought nothing of it and decided to leave it until patched but now when i've been doing some story missions (EARLY GAME CHARACTER NAME SPOILER) im looking for the detective valentine but whilst doing the mission i came to the vault he's inside and it did the same thing vault 81 did, won't open, breaks V.A.T.S and can't continue the game.

anyone have any idea why it's doing this or maybe a similar issue?

Okay, next time use white text, not dark grey on black, also, this is the wrong section of the forums.

Fortunately I had the same problem and fixed it. You need to keep your mouse over the control panel as there is someone talking to you and you have dialogue options. If you turn on subtitles you will generally stop missing these opportunities.

i have all subs on and no, no one is talking i didn't move from the panel thanks anyway tho.

did you're V.A.T.S stop working too?

Yeah it did the first time, but that was due to the fact the dialogue option was up, but because i was looking slightly away and it did that weird mouse drag thing it does when you try to move away from dialogue... Sorry it wasn't helpful, but still, should go to the Hardware/Software part of forum, or just wait for a mod to move it for you
