When I connect a computer to the computer port and trigger in loop getConnected(), it always returns true, even if I break a block of my reactor. Other functions, like getFuelAmountMax() still works like if the reactor would be a complete structure.

I also ran into this, version 0.4.3A for 1.7.10.
It seems that if you remove either a control rod or a fuel rod block, or any block under a fuel rod, it will return false, but otherwise it will still return true when other blocks, including the controller, are removed from the reactor. I added a computer port to a reactor after I had opened the top to change the coolant to diamond, but with the top still open it returned true until I removed either a fuel rod or a control rod block, or a block under a fuel rod.

Just some observations that hopefully help track down this bug.

i think that is because the reactor does not update the computer port unless the fuel rods / control rods are changed. unless operating that is.

i think that is because of the controler but this does seem like a glitch.
