To reproduce issue:

###Prerequisite:

• No Dock is used

1. Craft/give [Any] rank Dank
2. Take a note of ID
3. Add some items
4. Upgrade it to next rank using crafting grid (NOT Dock + upgrade card!)
5. ID gets updated along with Rank
6. Items you stored in Step 3 are now inaccessible

Wrong version, meant to post it to Fabric. My apologies.
