If I press R on the Prismarine Shard:

:concern: did I fuck up the tooltips somehow?

I did not change the chance, but if I do the problem still remains.

I made a change that might fix this. Can you give 0.1.7 a try and see if the issue persists?

This seams to have cropped up again. In v0.5.0 the recipe for Prismarine Shard says that it is a 30% drop from all waterlogged Mesh. While use of gravel in a water logged Iron Mesh is 5%. (unless this has been fixed in a version not posted.)

I can confirm, it was fixed.

I think I found the source of the bug:
If multiple sieving recipes for the same item show up in REI, the tooltip shows the chance of the last recipe rendered.

For example: The prismarine sieving recipe in Sky FABRICation 3:
Its chances should be:

• 5% chance for the Iron Mesh,
• 30% chance for the Diamond Mesh,
• 40% chance for the Netherite Mesh.

Window maximized, shows 3 recipes with Iron Mesh one being the last one:

Window minimized, shows only a Netherite Mesh sieving recipe:
