I just picked up the CPU Extender of my base to move it, and I found that the CPU is not affected. Shouldn't the CPU get downgraded once the extender is removed? If it isn't, we might place an extender to get the upgrade and then take it away and upgrade all our bases like that with the same extender, maybe even vehicles ... But it looks pretty. I the lights were blinking, it would look like a slightly wider version of my server rack ...
