Big news:
I am an idiot and forgot to tell the Thermal Beam to only do fire damage. However,
@Licflagg has used it to make a miner and suggested I keep the broken Thermal Beam around for that purpose. As such, the old version of the thermal beam will soon be rebranded the Plasma Beam, a shorter range beam which uses a modified thermal beam model and deals plasma damage. The original post of the Thermal Beam will contain both the new and old versions of the beam until I make the model for the Plasma Beam.
Any existing creations with the old Thermal Beam will have them replaced with the Plasma Beam once it's finished, the new Thermal Beam will have its own block ID.
