For a unknown reason, if anything in player.img is compressed, San Andreas will crash when CJ wears that item.
I tried it compressing his vest before and when I started a new game it crashed but when I uncompressed it, the game loaded up normally.
If your on about the Greaser safehouse, yes I did compress all the textures, it's just that there are so many!
It's a downside for Bully that is, because nft's like Z_terrain are so huge!
