EnderIO: Found the following problem(s) with your installation:
* The RF API that is being used (unknown) differes from that that is reported as being loaded (1.7.10R1.0.13 from ImmersiveEngineering-0.6.2.jar).
It is a supported version, but that difference may lead to problems.

Is there a way to find which mod actually contains the outdated API? I've deleted the energy folder from the cofh/api folder (as suggestion in the other issue conversation) from several mods yet I still can't find which one is causing this.

EDIT: Apparently I was misreading it, the second one listed is the old one, I thought the first unknown one was the problem...lol woops.

Also should be "differs" not "differes"
