Dedicated host 0.6Q crashes after loading layout with long name
attached layouts

Unhandled exception at 0x65646E65 in DCon.exe: 0xC0000005: Access violation reading location 0x65646E65.

I downloaded them to see what's the problem, and the issue is that the name is too long, that the layout on selection appears as:

A73_Touring Car Circuit Ex
A74_Touring Car Circuit Sh

Instead of the full names of the files, and therefor it doesn't let me select it to load, so I'd recommend to shorten that name, and try if it still crashes.
(Maybe you figured it out after 2 days, or not xd).

It's not possible to normally (in game) load such long named layout. It's not even possible to save layout with that long name. Your InSim app crashed your dcon host.
