Some of the prefabs arent spawnng

/maspawn building core/wall.doorway/wall.doorway
/maspawn building core/wall/wall
/maspawn building core/floor.frame/floor.frame

The shortnames arent working either, it just gives you the list of multiple matches

Some things are working, such as wall.frame, but i didnt go throught them all. Came across this trying to build a red card room around a pool of radioactive water in the Radtown. :)

Looks like those prefabs have spaces. You need to put quotation marks around the name or else it will be perceived as multiple parameters.
