Issue description:

I wanted to add Mekanism to the 1.7.10 modpack "Realm of Mianite", so I did and when I launch my client, forges loads since like 24% and then the client crashes. In the logs, it says that the SolarEvaporationController.class is not found...
I really need to add mekanism on the 1.7.10 version and I can't...

Forge: ForgeMultipart-1.7.10-1.2.0.345-universal.jar
Mekanism: Mekanism-1.7.10-9.1.1.1031

up ?

1.7.10 is no longer supported, move to newer version.

Ofc and that may be the reason why i can run the regular MC with the same version of mekanism, I'm asking help to fix my issue, I'm not asking some guys who say "give up"...
Thank you anyway for your answer but that's not this kind of answer that I want...

Fine, since Mekanism as is working fine, you will have to figured out on yourself the problem, start taking mods out and see when it stops. Or try to replicate the pack on yourselft, then you can copy configs or custom scripts if there are any
