I looked at the KMSP entries in the IAPs.dat (approaches) file, found in the FSX/P3D\Captain_Sim\navigation folder, and there is no SLIKK waypoint listed in the approaches for that airport. Not only that, there was no SLIKK listed in the entire IAPs.dat file at all (this is in the latest CS_1905 AIRAC from Navigraph). In my opinion, it isn't the CS 757 skipping the waypoint, but the fact that the SLIKK waypoint itself is missing from the Navigraph AIRAC IAPs.dat file.
