Yes, there is limit. The number of objects you can create is limited by your available memory and the memory that is allocated by the engine (i.e. the nexus). Try increasing the nexus and see if it works. If it should work, you shouldn't leave it like that though. 205 objects should normally not require an increase of your nexus unless the objects you create consume way too much memory (e.g. entities with way too many polygons, etc.)
