No king toots

Have you finished the quests connected to the previous buildings? I did a search on here for king toots issues and there are a few suggestions including storing Springfield elementary and having Principal Skinner free. I know it's time consuming, I spent many hours reading walkthrough and help threads (which are all great, there are some really helpful players who put a lot of time and effort into creating them), backtracking and storing buildings to get something to trigger, but it was worth it. If nothing works you may need to do as Muhsterino suggests and contact EA. Hope you manage to get it sorted, good luck :)
