What happened?

I've tested with multiple different reactors, alongside the simplest 3x3 in a superflat test world, all behave the same. I've also made sure to put uranium in the Solid Access Port when testing, also tested with both the passive and active FE ports.

The bug is that the multiblock never forms (the glass connecting visual cue never happens), even with the idiot-proof 3x3. The controller GUI cannot be opened with right-click/use because of this.

I realised what I was doing wrong, I was putting the power tap on the bottom face which is not allowed.

You are not on 2.24, please check again.

Sorry you're correct, I edited it to 10-2.23

I updated to 10-2.24 to test just in case, but it's present here too.

I did the 3x3 and is working fine.
