UPDATE: It may be pathetic to reply to myself for this, but...

From what I've been seeing, this appears to be a problem with ScriptHook not seeing the light of day in terms of updates.

I reinstalled GTA V due to it crashing every 5-10 minutes (in which I tried weeding out the problem, only for that to meet failure) - it finally stopped crashing... at the apparent cost of Online content not being recognized by the game, despite it being there (checked via OpenIV). Either way, I feel this might be a simple bug that might make me look dumb, but I do hope for a solution. GTA V has been running flawlessly after the reinstall, and I've missed out on having fun with the mods that bring Online content to single player.

This was also checked through Menyoo - which still works fine on my end, but it too shows the same problem.

To explain everything:
I absolutely love to fuck around with Menyoo - it's a go-to for me in SP in accordance to nearly everything I do in the game, and car customization is more than common. However, this is where my problem comes into play.
Some of the Benny's options on cars like the Primo Custom and Buccaneer Custom were greatly reduced for some reason - for example, no ICE or livery options. The customization options were somewhat cucked! It may be something to do with the game's code, but a fix would be greatly appreciated.

@Reacon No syntax errors found. Saved without a problem.
You're a godsend for this, thank you!

I don't know if this link may work on your end, but I've put the dlclist.xml (That's the XML where OpenIV's getting finicky) on Pastebin. It may be regular to you and me, but OpenIV thinks otherwise.

Recent XML issue I've been having in OpenIV, not sure if this has been discussed in the past but I've run into it quite a few times in the span of about 12 hours while trying to get GTA V up and running without it crashing due to mods.
Leaving it 'open' will just cause everything to go to shit and make the game crash, while making an attempt to 'close' it results in yet another XML error, and so the game could finally run - but without the mods, in which to me they add a whole new dimension to the game. Without them, the game would pretty much be bland.
Going back to the XML issue, a thorough solution would be greatly appreciated.

EDIT: Forgot to add, this may be a petty problem, but I tried looking at what to do about this and I could say OpenIV and the XML format are finicky when it comes to things like this.
