Best Left Forgotten

Best Left Forgotten is a quest in the Fallout 4 add-on Far Harbor.

Bugs

 * There is currently a bug preventing mission completion. On one's first entry to the simulation, it may be impossible to interact with the blocks one must move to make bridges & clear the path for the beam. Exiting the simulation and restarting the console may fix this. Furthermore, turrets are not unlocked for construction when the game informs you to construct them, making it impossible for the player's green decompilers to make it to the objective. This renders the quest impossible to complete, even after several re-loads and restarts. It may randomly fix on PS4 after returning to an old save. On PS4 returning to the simulation may freeze the game. There is a work around for this bug by using the blocks to imprison the defensive robots before they enter the area, trapping them where they spawn.
 * One can get stuck at 4th memory unlocking process where it would not go above 80% and then when one tries to exit the memory simulation, the game can get stuck where one can save the game but cant move around.
 * If you are stuck on the 4th memory simulation, leave the keyboard/controller alone until it changes as if you have left the computer. Once it goes to the mode where your character is looking around aimlessly, you can then move the character around.
 * Sometimes the orange data rings will disappear before the "bugs" are done with downloading the data. Making the quest impossible to complete.
 * If you leave the puzzle while red blocks are in the process of disappearing, the remaining red blocks at that time will remain, making it impossible to complete the puzzle.
