Welcome to GTA5-Mods.com

@SnakeVenom33939 See if any other mod you have installed is overriding "hei_po1_06_strm_0.ymap"
@JAM102970 Yes, they are a replacement for the "MP Map Static Collisions Fixes" packages (which should no longer be used)

@KSRfluffyboi Does it crash with a specific error? Which other mods you have installed?

@SnakeVenom33939 Did you install the new OIV packages as well (dumb question, I know)?
@JAM102970 The new packages are a replacement for the old ones, which now contain all the files and not just the YBNs (I forgot to write it in the changelog)

@SnakeVenom33939 Make sure you have removed the DLC packs with the "mp" prefix

@minimehan No

@KSRfluffyboi Which game version you're playing on? Does it happen if you install only the DLC pack?

@agio20 Download this content.xml, import it in "spMapFixes_Gen9\dlc.rpf" and check around the airport again https://pastebin.com/xHN51ifA

@agio20 Does the game crash instantly once you go, for example, to the airport or does it happen after some time of playing?
Also, try to turn off the ray tracing settings if you have any enabled and test again

@minimehan Are you loading a saved outfit or changing the jbib/lowr and other components manually?

@minimehan Did you try with MP Stub Patch installed?
