This map causes gmod to crash when I send client info after it downloads from server, using the workshop version does not fix this.

Strange, I just downloaded the map awhile ago and it loaded fine. Dunno what's up with your game.

Same.

I had absolutely no issues downloading it from the server. Try using the direct link on the workshop page.

If you get a Crash on map load try this below.

1) Temporarily renaming your "models" or "material" folders as they might be conflicting with the map in some way.
C:\Program Files\Steam\steamapps\Your-Steam-Name-Here\garrysmod\garrysmod

2) If above don't work Validate Garrys Mod from your steam game list. (Verify Steam Game Cache)
