The map has been updated to version 2, hopefully fixing the crash issue. Please let me know if the crash continues.

Change log
~ Fixed cubemaps being projected onto deleted brushes.
~ Reduced overall cubemap quality.
~ Reduced the size of some textures.
~ Removed unneeded light/shadow options from various props.
~ Removed Melee only trigger and filters.

The map has also been split into a DR_ version and VSH_DR_ version. The VSH_DR version can be found here - https://steamcommunity.com/sharedfiles/filedetails/?id=471833040

If you can't find the map after it downloads, it is because maps from this workshop get placed in C:\Program Files (x86)\Steam\SteamApps\workshop\content\440\<maps id number>

If you want to use the downloaded maps, copy them to:
C:\Program Files (x86)\Steam\SteamApps\common\Team Fortress 2\tf\download\maps

I will work on getting that fixed

I tested this on a server just a couple days ago
The map itself is fine, but some people experienced crashes. Some crashed while cycling throught spectator cameras, others by just selectign a team and a class.
