Huge build size / sprite packer broken in b21

Since b21 my standalone OSX builds are HUGE. In a project which was before 230mb, the build is now 1.66 GB. I haven’t added any files except some prefabs and scripts. I’m using a lot of packed sprites, but the editor log after building says that all the sprites are included unpacked. I haven’t changed any import settings of these sprites and when I press “Pack” in the Sprite Packer window, all the atlases are created properly.

I’m using a large amount of 16 bit textures. The only reference to these textures are in prefabs which are located in the Resources folder. The textures are NOT in the resources folder, so they should be packed.

Was this reported already?

I’m also experiencing this on iOS – nobody else has this problem?

OK - I dont know what the issue was, but deleting the Library folder and reimporting all assets fixed the problem.

Edit: It only fixed the standalone builds. The iOS build is still much bigger (x10) than before, at least what it says when clicking “estimate app store size” in xcode.
