I tried making sure it wouldn't install 1.3 mods and then decided to try doing it manually. This originally didn't work, but I tried your suggestion to use it from GitHub, and it worked.
There was a caveat though as AJE wouldn't allow the Panther engine to be loaded as it said it couldn't find the resource Kerosene. I did have RealFuels installed. I removed AJE and it worked well though.
Aside from that, I did notice there were parts that started with "#autoLoc", although I assume that's just because it from the master branch and not a release. Thank you for the help so far.
