How to solve the Fallout 4 Vault 111 Re-Entry bug. Not sure if this works for Xbox and PS but it is confirmed on the PC. I did not use the Dogmeat glitch to get the Cryolator in the beginning of the game. Once I leveled up to a Master Lockpick, I could not get back into Vault 111 due to a glitch in the game. Last night, I solved the glitch and made this video to share! Hope it helps you too!
