Make killswitching the AI not destroy the core

[BaneOfGiygas]

Actually it's pretty damn hard to get to the AI core without wrecking half the AI chamber to get rid of the inner turrets and disable the inner APC so you can crowbar the blast doors open.

This, pretty much. If you don't have the ability to just tell the AI to allow you to debrain it, which you won't if it's rogue, getting into the core tends to be really hard without pipe bombing the place and calling it a day.
