What people expect from this housing blunder.

I expected developers with 10+ years of MMO development experience to be able to properly code and execute a basic random number generator.

I guess that was too high of a bar.

Obviously you aren't a developer in any regard. No matter how easy a system is on the surface, you can't always account for every single bug that can occur from it. Even if you test it in a private environment, implementation on live servers can still cause issues. It's the same reason why you get Windows updates but, said updates could cause various units to malfunction around the world. Doesn't mean the overall update wasn't tested well enough. Dev 101, and literally a case for every company everywhere.
