[Bug]: 1.21.1 When making a pocket in a pocket, other pockets get overwritten

[ChanGrape]

What happened?

After updating to the latest 1.21.1 version, all of my pockets are being overwritten whenever I put a new dimensional door inside a pocket. It's as if the mod doesn't know that a pocket in that part of the pocket dimension is already being used and reassigns it to a new door.

Mod Version

6.2.1

What versions of Minecraft does this issue happen on?

neoforge 1.21.1
