ParticleSystemDestroyer.cs causes errors in cloud development.

Hello,
I don’t know exactly when I downloaded the utility package, and when I needed it for my game, but ever since I downloaded the utility package, I noticed that I have received failures in my Cloud build. I tried deleting ParticleSystemDestroyer.cs, and got compiler errors. Then, I tried commenting out

'namespace UnityStandardAssets.Utility
{
}

because I got something like …

‘The type or namespace name ‘Utilities’ could not be found (are you missing a using directive or an assembly reference?)’

and got other errors in my Cloud build. I have un-commented it back to normal and noticed that I have made so many attempts to develop my game in Cloud build, that it is in ‘cooldown’ mode for 30 minutes. When I build my game from “Build and run”, I get no errors. What is happening?

Thank you,
Michael S. Lowe

Is there a way to ‘force’ a successfully completed game that is made from the “Build and run” process, into the Cloud development build?
