It makes sense to be able to spawn any object in the project, and this feature would be a HUGE help for level editing.
Of course it probably is a technical problem that I have no experience with, but I was just wondering how that is going/if scirra intends to fix.
EDIT: It seems I just spawned an object not on the current layout...
Either Scirra fixed this under my nose or I an very ignorant ;)
Probably both ;)
