Well, took it apart - interesting failure.
Looks like the friction disk springs were rubbing on the flywheel bolts, the friction disk itself is all wavy, and the edges of the pressure plate side are pretty much all gone. The disk is thin metal, almost sheet metal - looks so light and flimsy. Clutch has 1500 miles and maybe 6-10 passes on it.

Did teh clutch kit come with the ARP bolts ?
IMO, they really are **** and unnecessarily tall. I had issue with my triple ExoSkel years ago when there were no instructions supplied with the kit to state ARP bolts cannot be used and you had to use stock.
Although the clutch disc fouling on the bolts would only cause dragging making it difficult to change gear.
Maybe it was also strong enough, substantial enough to prevent the flywheel side fully mating to the flywheel ?
Although it's obvious you've had contact, it'd be hard to see how it actually caused slippage to the extent it would burn the **** out of the organic disc.
When I changed to my current triple disc clutch, I used ARP flex plate bolts instead as these have a shallow had more akin to the stock bolts.
But no way in hell should a single disc setup have this problem
On the budget side, some new bolts and a new friction disc should let you away although if it was supplied like that as a kit, there would be warranty possibilities.

Who installed it is less relevant....exactly what was supplied and by who is more relevant.
Although it is something that should have been spotted at assembly stage considering how bad it seems to be. Especially an experienced professional.

Seeing your premature clutch failure due to someone else's negligence sucks.
Using ARP bolts to make an extra few dollars profit was a clear contributor to the failure of your clutch since it prevented full engagement of the clutch disc. I've had great success with Mantic when installed properly. Hopefully you're using someone that knows what clutches can use ARP bolts to install your clutch this time.

Although he still hasnt stated whether the ARP bolts came as part of the kit or were fitted by others.
But there is absolutely no excuse for a company making a single disc clutch that cannot use the ARP bolts. That's just bad design on their part when every other company can do it ok

There are other quite a few clutches that I’ve seen that cannot have ARP bolts installed with them. I don’t fault the clutch manufacturer when ARP makes them so ridiculously tall compared to OEM. I’ve also never seen any issues with using OEM bolts. I’m confident that Mantic didn’t include ARP bolts because I know the nat’l rep for Mantic and he’s well aware of the issue with using ARP bolts and personally sets up the clutches sold in the US.

I've seen the problem before with a multiplate clutch....although also used multiplate clutches that had no issues with ARP bolts ( ACT )
But singles ? There's a ton of room if designed correctly.
But also fully agree the ARP bolts are *****. There is no need for them to be so tall..and at the same time also have such poor spline engagement for the socket.
The ARP flex plate bolts are far better in every respect.
But for the OP...he just needs new bolts and a friction plate and he should be good to go
