Unfortunately, admin_ai was never finished. It tries to spawn the AI where you are looking, so you can try looking somewhere where there is space for those entities to spawn. That message means the command can't find a clear space to spawn the entity. Admittedly, it doesn't try very hard.

You might have better luck with e_add:

Code:

e_add npc_rollermine origin %HERE%

I don't mean to be the bringer of bad news, but that command isn't implemented in the released version of SoureOP.
