I tried installing a mod for TA called Total Mayhem off of ModDB, but when I ran the batch file to install it and looked in the game, there were no new units added. The title screen showed "Total Mayhem" but I saw no new units in the game and there were more blank spaces on the build menu where these units should presumably be. This also happened when I tried adding other custom units. Is this because those units are mainly on higher build tiers? Total Mayhem is supposed to have a lot of units and I presume those are supposed to include units on tier 1 too, which is what I should be seeing.
