I am going to wait and see how badly I need 30 points from the April 29th and May 19th Barn Upgrade tasks. (The Chest rewards and/or point requirements may not make a second barn upgrade worthwhile for me.)

I don’t mind doing another Professor Verne for the barn upgrades so long as its not tied to yet another colour splash event, it’s been tedious, difficult and expensive. I guess you learn from experience, lol.
