So I've hit a bit of a snag.. I figure if I can't figure it out, ask someone smarter. So here's my question, is it possible to have too many model replacements in the game? If so, is there a workaround? I have the steam ver of SA downgraded to support mods. I have a remaster mod that basically just makes it a bit prettier. A skin pack that replaces almost all peds in game. I was individually replacing GSF gang members when I noticed no changes were being made all of a sudden. I was using spark img tool, also tried IMG 2.0 and the other ALCI. I was saving, rebuilding, and double checked each time that I was on the correct game file. For whatever reason, no changes are being made. I have never had this happen before. I had the same set up and had replaced nearly every car in game with HD real life cars and ended up screwing something up and the game would not run anymore. Game still runs fine, just no changes. Any thoughts?
