I am having some problems with the sprite batcher. I have been away from my project for some time and when I booted it up I had way more draw calls than I used to (where I used to have around 8 I would now have 1200). It seems that after I updated unity to 4.2.1f4. Almost all of the sprites I use are from the same collection but each counts as a new draw call.
I have tried reverting to a much older version of my project to test if I had randomly clicked something to change this but it also displayed way to many draw calls.
Is this a known error or am I the only one experiencing something like this?
