Bug: Disappearing Grass Side Tables

Playing on the new PTB, I've noticed that my grass side tables are disappearing upon loading a save - both previously placed and newly built.

Typically, I save my old weapons and unused trinkets in grass side tables in my base's bedroom. After playing the PTB for a few hours, I went back to my base, and I noticed that those grass side tables were gone, along with all of those weapons and trinkets. Fortunately, I had a backup save from far enough back that I was able to recover all those items, only losing the progress from today. After moving the items to regular chests, they're no longer disappearing, but any new built grass tables will disappear.
