I was having trouble getting the Barrel to work in the blueprint. It kept resetting and I had to do everything all over again. Finally, after 5 tries, it took. I had the barrel where I wanted it and it was there each and every time. The new problem was that I could not get the “Logging” to work. After some searching I saw that I forgot to put the barrel into the blueprint again. So I had a visual showing the barrel in the correct spot but the controlling blueprint was empty. This in turn made it so that I could not get the log to work.
Put this out there in case someone else has an issue with the blueprints.
