[Forge for v1.20.1]

The mod breaks the tooltip of the Metal Bundles mod. It flashes shortly and then disappears.

Normal UI:

With the mod:

It also breaks the Vanilla Bundle tooltip.
Without the Metal Bundles mod the tooltip flickers the bundle's inventory in and out.

Can you verify if this is still happening with the latest versions of Iceberg and Legendary Tooltips? I've done some testing and I can't reproduce the issues you describe.

Actually I just noticed you have the 3D item preview enabled with bundles and I can confirm when the preview is turned on I get this behavior as well. I am working on the fix now.

Good news, I was able to fix this with an update to Iceberg. Version 1.1.18 should resolve this for you. :)

Wow! Thank you so much!
