Anyone else having issues with their staircase bookshelf failing at the staircase part? I put two of them side-by-side between partitions to make legit stairs, and prior to 5.5, they worked fine. Now, there is no smooth transition on the incline -- you have to jump to start running up them. On top of that, a third of the time, I literally slide back down the stairs; the other two-thirds are split between falling through the stairs completely, and getting lucky enough to successfully scale them as intended. Was the intention to have gimmicks like this no longer viable? I'm torn now, because the wooden steps don't fit my aesthetic.
