^^^^ This version is incorrect
Note: Version dropdown on bug report does not list current modpack version (I use "Recommended" which appears to be v1.2.0)
What is the bug:
Tried to load up and run the "Horizons Daybreaker" modpack via the FTB Launcher, and I got this message as the loading process was happening, which halts everything and I'm forced to use the "Kill Minecraft" button.

"Forge Mod Loader has found a problem with your minecraft installation
The mods and versions listed below could not be found
Mekanism: any
The file 'logs/fml-client-latest.log' contains more information"

I can past the log if needed.Why is Mekanism not being found, is there a problem on FTB's end, or do I need to do something on my end?

Mod & Version:

Can it be repeated:
yes, every time it fails with same message about missing Mekanism mod.

Known Fix:
