I want to rearm a map called dm_stripclub but every time i put a spawn down it crashes hl2.exe. Are there any specific causes for this?

Map: http://www.fpsbanana.com/maps/146061

The map crashes gmod for me

With the update of gmod, i recently opened some of my rearm scripts to notice all my spawns set were gone. I put the spawns back the way they were, but some of them didn't save rotation, is this happening with everyone?
