I have been working on a game for 3 months and no problems. Today I get these errors when using window 86/64 platform and I build the game. I am using windows 10, unity 5.2.1p1, on PC/mac platform and export as window 86/64 windows
Cannot load Atlas During Build/Enter Game. Missing File ?
Failed to add the asset file size for sharedassets0.resource

I have the same problem but on win 8.1 so its not the OS. Its the engine. There are additional issues with lighting. You have to turn off Baked GUI and at the bottom uncheck automatic and make sure its not there in Objects under the lighting also. Otherwise it will try and build a scene with nearly nothing in it claiming it have some 60 or ore jobs. I tested this to see how long it would take for it to completely build. It gets done within a minute. But with those baked and auto settings i came back literally a day later and it was still trying to “finish the jobs”.
The latest version 5.2.3 (or patch version: 5.2.1p4) got rid of it.
