I purchased a Beaver Stump and placed it. When I tap on it, the Beaver Bait appears for me, but when I tap on the bait to put it on the stump, nothing happens. If this matters, I only have 4 bait at the moment. Game has been restarted, and I bought the stump last night, so I have waited it out a little, too.
(This game is played on a different ID than the one I use for forum.)
