While driving home, the navigation kept leading me off of I-55 onto minor highways. This morning, I discovered that two problems.
Along I-55 SB south of Como, this mode has through interstate movement not allowed.

One section of I-55 SB had been replaced with a simple street. The node at the next interchange was locked resulting in no turns allowed (through or exiting) at this exit. I restore the interstate because it is unlocked, but turns need to be allowed at the node.
