Hello folks -- Testing mods for upcoming OP Landslide -- ran into these errors. After reading, reading and re-reading the readme text, I'm going crazy trying to figure out what I messed up -- disregard aia_baseconfig.
As per MAJ Drumheller's instructions, all I did was add the @OPLandslide folder.
NOTE FOR 506th MEMBERS:
The ONLY file you need from the modpack is @OPLandslide. All other files are identical to the 506th pack.
Any insight would be greatly appreciated!
