Here's a screenshot of the code that pastes the sprites into the Paster object. What it does is pick a canvas with the same ID as that assigned to the sprite's layer (defined in varibles in both the Paster object & sprite), pastes the sprite into that Paster object, then deletes itself.
It works fine w/ 0.4, and also works if I'm using Canvas objects instead of Paster objects (it's just a LOT slower). It just doesn't paste the sprites using 0.5. I've also tried it on multiple machines, Windows 7 x64 on three of them (nVidia GTX 750i, nVidia GTX 770 Superclocked, nVidia Quadro K5000M) & Windows 8.1 x32 on another (Tablet PC, not sure on GPU).
