Not sure what is happening exactly, but it seems that whenever I edit the dlclist.xml file in OpenIV as outlined in the description, the game crashes whenever I go to load up story mode. I only have LSPDFR, ELS, and this pack installed. I've verified the game files which resets the dlclist.xml file and the game works just fine but I'm not seeing any of the cars. I also chose the add-on pack instead of the replacement one. I'm very new to modding GTA so I wouldn't be surprised if I'm missing something. I'm able to get a crash report if needed.
EDIT: Just gotta install an updated gameconfig file
