I dont know if this is supposed to be a bug, but while i was messing around in the scratch editior i made a vector sprite that automatically resized to a certain percentage. Why does the scratch editior automatically resize sprites like that? I couldnt resize the vector sprite past that limit it made. Heres what im talking about:

The image in question:


How big is your sprite? Sprites have a minimum and maximum size. If you want to go beyond the size limit, create a smaller costume where the size you want is within its bounds, set the size while the sprite is displaying the small costume, then switch to the bigger costume. As long as you don't use an size-affecting blocks, the size will remain at that percentage.
