After exhaustive bug finding via removing scripts and assets one at a time and seeing if the mod would load then replacing them and repeating the process, I have discovered that the file that is causing the hang up is RKFrepair.txt.
The mod will always load in the mod loader near instantaneously as long as that file is not present.
I've already begun playing with it to see if I can find out why that file is causing so much trouble. Preliminary testing seems to indicate that it has something to do with the amount of "fixing" recipes it contains (I removed all but one and it loaded fine, replace those entries and it hangs again). I'll keep working and report back once I've figured out what's going on.
Edit: I found it! It was an embarrassing rookie mistake... I forgot to close one of the sets of { } for one of the repair recipes. Thanks for the help everyone. Hopefully I can finish testing now and release this in the near future!
