I have this error in the 0.17.3 version:
Failed to load mods: error in assignId, item with name 'advanced-processing-unit' does not exit.
Source: electric-boiler-4 (recipe)
Mods to be disabled:
• electricboiler

That happens because you don't have Bob Electronics mod installed along with the other bobmods, gonna fix it to be a depedancy on next release.

Just a quick update on the development of this issue:
I still couldn't find a reliable way of detect bob's mods that doesn't have bob energy stuff. Once I figure that out, I'll toss the update.
The idea here is:, if not all the depedancies are present, the mod won't enable the other variants. But detecting that you have bobmods but not bobmods.electric-boiler-4 is still giving me trouble

Should be fixed in this next version
