Teleporting Entities doesn't work?

I'm trying to use the Request_Entity_ChangePlayfield command but no matter what I try my entities will not teleport to another playfield. Is this broken or am I missing something?

 

Both playfields have to be loaded.

 

Awesome thanks, its working now.

Do you happen to know how to determine if a structure is powered on or not? GlobalStructureInfo.powered returns false regardless of the state of the power switch in the menu.

 

Using Request_GlobalStructure_Update worked, the API2 method and Request_GlobalStructure_List methods do not work to determine powered state.
