One of the great things about EDA Playground is that it is possible to share code by sharing the URL of that code. This is useful when you are asking for someone's help and is easier than pasting code into a message. Anyway...

I don't think this is an error with your code. It is an error reported by the simulator itself. (I did an upgrade on the servers today; I expect it's caused by that.) It looks to me like your code is working fine.
