Issue description:

Thermo generator upper then Blazing Not Working

Steps to reproduce:

Thermo generator Niotic/ Spirited / Nitro, Block of crystal, water source

Is this a crash?, please includ it here: (Recommended to use Gist)

...

This is happening for me on ATM9.
Minecraft: 1.20.1 ATM9
Powah: 5.0.5

I believe it is a block update issue.
@SergeTDU Try replacing the cable you are using for output to force the generator to update.
When I mined up the cable and placed a new one it went from 0% to the proper 280% for blaze crystal.
I looked through the config and verified the block ID, so it is registering the heat sources.
My guess would be something in the .class is not registering correctly, but I didn't dive that deep.
Hope this helps.
