Issue with 14.0 Replenishment proration with substitute items

Is anyone experiencing issues in 14.0 when replenishment needs to proration inventory across multiple stores when the item being replenished contains a substitute item?  There was a previous issue in 13 that replenishment would proration inventory incorrectly when the warehouse  had insufficient inventory and substitute items were involved.  In this case all the available inventory in the warehouse would be assigned to the store with the highest store number, even to the point where the store would get more than needed, and none of the other stores would get anything.

This has been fixed in 13, but it seems to have re-appeared in 14.  Has anyone else seen this issue in 14 and have you been able to work around the problem.
