Hmmm, don't know what to say. I had a bunch of mismatches so I eventually just totally uninstalled INF and UT, then reinstalled UT and the patch, then INF 2.86. I then installed the map packs after that but kept getting mismatches...most of the maps wouldn't even load. I then went into the Infiltration directory and saw that the 2.85 Map Pack had created it's own map, texture, music, sound directories in the Infiltration directory. So basically I had 2 folders for Maps, Textures, Music, and Sound. 2.86 was looking for the textures in the old directories, INF_Textures as opposed to the newly created 2.86 directory which is just "Textures" as opposed to "INF_Textures."
