Bugs

Prior to patch 1.0.3.10., it was possible to rapidly press the final "master shutdown" button and receive the reward multiple times for completing the quest.^[verified]
The Alpha and Beta keycards will always be dropped by the Mister Gutsies inside the bunker. These keycards do not stack like normal keys, and picking up multiple copies will lead to irreversible inventory bloat.^[verified]
The keycards are not necessary to complete the quest.^[verified]
