Unfired large vessels are heavy/huge, while fired vessels are Medium/Huge.

In Classic, they were both heavy/large.

This results in gaining the massive debuff when carrying more than one unfired large vessel:

I understand sealed large vessels having this impact, but I didn't think it was intended that unfired large vessels have the same impact?

The resolution in this case is actually to make them Huge / Medium:

• It matches the current large vessel (which becomes huge / medium, or huge/heavy if sealed)
• Huge means it can be placed in the pit kiln as a single item, rather than four.
