A couple of considerations: STK is a module, not an add-on. Have you created the game with the module, or used the map pack add-on. (hopefully you haven't done both, since this can mess up a game). The fact that you can drag in a fresh compendium creature but not an STK creature leads me to believe that something has happened to the default tokens in the game. If you drag in a compendium creature, it will not overwrite a resident copy (in order to prevent losing any homebrew or personal modifications). It only places a copy of one already there. This makes me think that something has happened to the creatures resident in the game. Adding the Feylight addon should not have affected the STK content in any way. Some things to try: 1. Create a fresh STK game and see if the tokens work there. 2. Open a creature from the problem game and click the edit button. Verify that a default token shows on the edit page. You can try going through the troubleshooting steps I'll list below, but you've done most of them. Step four will give you the procedure for capturing a console log, which will help a dev figure out what is going on.
