ID:171028 Can't place the following nodes in a carry chain -- cannot find a common child Logic Lock region

CAUSE: You assigned one or more nodes in a carry chain to a Logic Lock region. When placing a carry chain that has Logic Lock region assignments on the nodes in the chain, the Fitter finds a common child Logic Lock region for all the nodes in the carry chain except the first node in the carry chain. The Fitter then places all the nodes in the carry chain in the child Logic Lock region. However, the Fitter cannot find a common child Logic Lock region in which to place the carry chain. Click the + icon to expand this message in the Messages window or in the Messages section of the Report window to display details about the nodes that have Logic Lock assignments and all of the nodes in the carry chain.

ACTION: Remove the nodes specified in the sub-messages to this message from their respective Logic Lock regions.
