Some npcs don't work

[flamdar]

I have never tried to have npcs in one of my maps until now. I put a zombie in but right when i get into the map the game crashes. I tried one with an alyx npc and it worked. Do i have to do something else to get enemies to work?

Hmm, what game are you compiling for? Is you npc_zombie stuck in the floor/wall? Does your map have info_nodes?

I dont have any info_nodes. i'll try that. thank you.
