Packing Tape mod and Placeables used to be compatible, but Placeables now causes Packing Tape's packed chests to turn into copies of each other. Packing Tape hasn't changed since when these mods played nice together, so it has to be something changed by Placeables.
How to reproduce:
1. Enable placeables and Packing Tape mods
2. Start or load a game.
3. Make sure packing tape is toggled on in the quick tools.
4. Place two chests.
5. Put different items in each chest.
6. Pick up both chests
7. Open the inventory
8. Select one of the packed chests
What I expect to happen:
The selected packed chest goes into the cursor, and the other packed chest stays as is.
What happens:
The other packed chest turns into a copy of the selected chest.
