Yes I did import the PUN add on as well. Are there further steps I need to take in order to clear the warning?That warning looks independent of the Deathmatch AI Kit. Did you import the PUN scripts? There are scripts in the folders beneath those add-on folders.
Solved: Restarting the editor clears the warning. Seems like an import time warning. Will update if anything else comes up later.No, there aren't. Have you tried a new project with just importing the character controller and PUN? If it still shows the warning you should submit the bug report to Unity.
