What mods, especially Bob's mods, do you have installed?

I managed to get same error (except it disabled both spacex and angelssmelting for some reason), having installed all Bob's mods except clock, character classes and personal equipment and all Angel's mods. Adding Bob's Personal Equipment fixed the issue.

I agree fully with Asm_Nh: On my system both spacex and angelssmelting had to be deactivated with that error message. Adding Bob's personal equipment does fix the issue. Were there some changes within Bob's mods that SpaceX is not aware of? And why on earth is angelssmelting affected, too?
[Edit:] I also do not use Bob's character classes, but all the other of his mods – together with all of Angel's (except decorations and locales)

Bob must have moved energy shield mk3 to personal equipment. No idea why any angel mod was affected. That is a factorio bug. I will fix the dependencies.

Bob made a new Mod and shifted some recipies into that. Just install the following. Works for me.

Did what Skeadr suggested and worked like a charm, thanks!

Ditto yep with @skeadr!

I will fix the dependencies this weekend - meanwhile just follow the excellent advice as given above.

Fixed in 0.4.4 - you need to use Bob's personal equipment mod now to activate the Bob's recipes. Bob's warfare is not required (but is optional).
