Cook Failure

I am trying to Cook my game and it keeps giving me ‘ExitCode=25 (Error_UnknownCookFailure)’ after a few minutes. I am honestly at a loss for what is going on, any help would be greatly appreciated.

Your log contains plethora of blueprint invalid pin errors. Find and fix them and see if it works.

Thanks, I was able to go through and clean out the problem blueprints. Works great now.
