mekanism is missing blocks in 1.16.3

The fusion and reactor casing and solar panel and other blocks are missing in 1.16.3

i am using forge 1.16.3-34.1.24.

the mod version is 10.0.15.441

And also all of the names of the blocks have changed.

Install mekanism generators, this has been needed since 1.7 or maybe even earlier to have the generator blocks
