First, Thank you for back porting AA! I really love item lasers and interfaces. So when I was playing the pack Imposter Syndrome, I noticed that the lasers were not appearing at all. After an hour of moving mods around, Blood Magic seems to be the culprit. Not sure why? I did notice it was using some kind of datapack and when you remove blood magic and load up the same world it becomes invalid/corrupted.

How to reproduce: Have any instance contain blood magic and actually subtractions, load up world, place and connect two lasers
Expected result: Clearly see Laser line between relays

Versions:
ActuallySubtractions-1.20.1-1.2.14.14+mc1.20.1
bloodmagic-1.20.1-3.3.3-45
