This seems to be a problem with Railcraft's aura block
This happens even with Railcraft not installed, but only on blocks that were placed when Railcraft was installed.
Reproducing this bug is rather random, the way I managed to get it to crash was using a Magmatic Dynamo and placing it straight down while crouch-jumping, which replaces the aura block with the dynamo, and then right-clicking on it to open the GUI. Unfortunately this doesn't always reproduce it. But once the block crashes you can uninstall Railcraft and the same block will still crash, but no newly placed blocks will.

I've submitted this on Thermal Expansion and Forge's side as well, seeing as how a similar bug was fixed in 10.13.0.1199.

Update:
Setting residual.heat to false in the block config fixes this.
Thermal Expansion has stated that this is either Railcraft's or Forge's bug.

It would certainly seem so from the other issues. Thanks for looking!
