The best way to describe this is just to say that using a personal pocket via a quartz door doesn't always stay put. You can leave the dimension alone for a while and come back to a completely new pocket, the previous pocket still exists but the only way to get back to it is to teleport to it via text console to it.

This is already fixed in the latest dev build.

Can we re-open this? I have the latest version of the mod and this is still happening!

@rll18 refer to #85 instead and note that the issue may already be resolved in the current state of the source code. We just haven't released a new version yet.
