Items getting empty "tag" field in NBT causing them to not stack properly

Describe your issue.

Environment

Server: Self-hosted

Mods Involved:

  • Create (Item Vaults)
  • Ars Nouveau (Storage Lectern)
  • Applied Energistics 2 (AE2) – upgraded, but issue persisted
  • CreateStuffAdditions Fix – installed, no effect
  • Occultism (Dimensional Storage) – replacing Create vaults eliminated the problem

Problem Description

With one Create Item Vault linked to the lectern, items transfer and stack correctly.

Adding a second vault leads to intermittent split stacks of identical items.

Inspecting block data (/data get entity @s SelectedItem with item in hand) shows one stack carrying an empty NBT compound (tag: {}) while the other lacks it.

Reproduction Attempts

  • Observed consistently on the self-hosted server.
  • Quick test in a local singleplayer world did not reproduce the empty-tag behavior.

Troubleshooting & Workarounds

  • Custom KubeJS Script: Removed empty tags from inventory; tags reappeared after some time.
  • CreateStuffAdditions Fix: No change after installation.
  • AE2 Upgrade instead of the lectern: Did not resolve the tag issue.
  • Occultism Dimensional Storage: Swapping to Occultism’s storage completely prevented the empty-tag stacks.

Conclusion & Recommendation

Create’s Item Vaults are injecting an empty NBT tag on some transfers, causing split stacks. As a reliable workaround, use Occultism’s Dimensional Storage until a fix is released for Create.

This is a pretty major mod issue that seems innocent, definitely needs forwarding to create if that hasn't been done already.

Thanks for the report! Would you mind forwarding this to Create directly? 😊
