@CMendez You installed prerequisites (heap adjuster and packfile limit adjuster)? And it doesnt matter if you have much or few mods, probably one mod is outdated or not working.

@Manuel138i have everything needed, and no mod is outdated lmao,

@CMendez Can you tell me your mods if they are few? Or you have so much mods? :)

@Manuel138 I tried your gameconfig for last version and it works fine，but with this version it crash my game. Will this mod have another update later?

@gentlejoey123458 what do you mean? The lastest version crashes your game? You installed latest version of pack file limit adjuster?

@Manuel138 I tried the gameconfig made my two other authors and seems like they both didn't work. I haven't use your gameconfig yet but will have a try tonigjt.

@gentlejoey123458 Packfile limit adjuster has updated (if you dont know that please install the newest version), and other mods like simple trainer too, try installing the lastest version of the mods that you are using and tell me if it works

@Manuel138 I know all required files，but thanks， WI'll try them tonight:)

my game worked well, but after 30, 40 minutes it crash.

@AlexSouza993 Um, probably there is a mod that makes the game crashes, can you tell me some of your mods? (tell me mods that you think that it causes problems).

@Manuel138 NVE, something like 500 cars, weapon pack sound, ENB by NVE, rob fleeca, vangelico, pacific standard and paleto, i think it's this.

@AlexSouza993 WOW, 500 cars? My gameconfig doesnt have that capacity...

Guys, I just solved the problem of the game unlimited loading or crashes after you drag new gameconfig.xml into your old mods/update/update.rpf/common/data

You will see a file, version.txt, inside the common/data of both update.rpf and update2.rpf(or just inside update2.rpf), you open it, will see these terms:
[VERSION_NUMBER]
xxxx-dev_ng_Live
change the xxxx into the current version, 2699
[ONLINE_VERSION_NUMBER]
x.xx
change the x.xx into 1.61
and your game will loaded perfect after you install a new gameconfig.xml

You don't even need to reinstall the game and mods, just change the values and everything works!

@560877 You can change that text version to anything you want and the game will still work perfectly fine. Changed those numbers to random and still loads without any issue. Just stop lol..

@Tixer Well I'm sure that if I put the new gameconfig without change the number, the game just loading forever, after I change the number game just loaded, so I think that's the way, but just having some error in some areas causes the game crashes, still trying to figure out

hey man it didn't work for me but its not your fault and you did share it just to help others and btw keep up the good work man God bless you!

@toolkithelix Thanks man, you tried wit others or only mine dont work?

@Manuel138 yeah man but didn't work for me also but its okay for me lol

the thing that worked for me is going into mods/update and delete update2.rpf then go to the same path outside of mods folder and add it back into mods folder. also using this gameconfig
