Error after loading day 3

[shanepadgett]

Each time day 3 loads I get the following error.

InvalidOperationException: Collection was modified; enumeration operation may not execute.
System.ThrowHelper.ThrowInvalidOperationException (System.ExceptionResource resource) (at <fb001e01371b4adca20013e0ac763896>:0)

Hey, it's probably one of the enumerators underlying data sources getting modified somewhere, will take a look when I get a chance.
