I had a look at the code, the reason for the crash lies in Brandon Core: It uses the return value of getCapability() without checking it for null.

Note: The energy capability for the creative CapBank has been disabled because some mods could not cope with its unlimited energy.

Ok, cool, posted this on their Github 2 days ago with no response yet. But Brandon is most likely uber busy so I won't stress this too hard, a friend pointed me to NTB Explorer and I deleted the capacitor bank out of my inventory and got my world accessible again.

@HenryLoenwind Actually this entirely on EIO. along with "getCapability" there is a "hasCapability" method. The entire purpose of that method is to check if the item has the capability before trying to access it. If something reports that it has a capability then it MUST provide that capability otherwise the hasCapability method is completely pointless.
When they disabled the energy capability on the capacitor they forgot to return false in hasCapability. This is why its crashing.
