Steps to Reproduce

Build following reactor:
Fully-formed reactor view:

Reactor view without the top lid:

Reactor view with the top lid hovering above:

Reactor bottom view:

Whenver you try to toggle on the reactor, the game crashes. I've tested this 5 times with different configurations, introducing any kind of fuel rod, coolant or simply run the reactor empty, and it still crashes. I also tried doing different types of reactor configurations also used the JEI multiblock preview reactor and it will crash if I use any fuel rod input/output in it.

Additional Information

World is irrecoverable after crash.

Trying to reproduce, it really crashed irrecoverably with other similar designs like this one:

This Setup, with only coolant channels and ports also causes the same issue:

Setups without cooling channels don't cause this:

But as soon as i added cooling channels and the coolant ports it crashed the game

Seems that it is the issue of the coolant export buses.
