Hi Travis,
There are limits associated with the consistent behavior of shared links associated with the size of the CODAP document. Large shared documents take longer to load and can trigger a timeout.
Story Builder makes it easy to create very large documents! While Story Builder attempts to keep the document small by differencing from one moment to another, sometimes this differencing isn’t possible and you end up with, essentially, copies of an entire dataset in each moment. These copies can make the document large.
Take a look at the size of the troublesome document. Then consider rebuilding it from scratch. It’s possible that in so doing Story Builder will do a better job of preventing large copies of datasets from appearing in multiple moments.
Hope this helps,
Bill
