It took some trying to get working, but once it did, I was filled with so much happiness. Thank you for this tool. For anyone struggling to get things to work, here are a couple snags I ran into (because of certain parts of the instructions that I misunderstood- totally my fault):
In Step 7, the ID number of Follower_Common_Event is a number you find near the top of the script section "Follower Config", the one you put above Main. The ID was "5", for me. That means I had to put "pbTalkToFollower" in the 005 slot of the Common Events in my Database.
Also, make sure that the event you use for Step 9 is not the same event you use for step 8- Step 8's event has to remain blank, as far as I can tell.
All of this was made clear in the instructions, but I figured maybe this could help someone who runs into the same snags I did. In any case, this tool is truly wonderful, thank you and the previous Follow Pokemon version developers!
