FI Ghost, someone (makman94?
I'm not sure
) did a mod which adds a big compass to my GUI, but I don't know if it is up-to-date and compatible with the latest version of my mod. Hopefully he/someone will read this and answer your question with a link.
Shakatan, install OLC first then let the other mods overwrite it. As long as the only files being overwritten are the ones you named, it should be OK. Those pages in your recognition manual might look a bit strange, but no other conflict-related problems should arise.
