Solved Milk glitch

v1.6.15 build 24317
I recently built a display for all of the items shipped and put them on modern end tables. For some reason after some time passes the small milks and sometimes the large ones for both goat and cow varieties turn into mystery boxes. You can see it in the upper right corner. Not sure if my save file is corrupted or if this a item id issue.

Were they on the tables on the night of Winter 24?

Yes they were. It's strange because it doesn't happen to all of them at once

That's a little easter egg!

Winter 24th..... leave milk out..... receive wrapped up box the next day in exchange................

Ah I see, thank you that makes so much sense now.
