Can confirm in 1.20.5-rc2.

Relates to MC-270707, I suppose.

Can confirm.

Potions that give level 1 effects dont show the numeral after the effect, e.g.: a Potion of Night Vision gives, as shown in the item, "Night Vision (3:00)", not "Night Vision I (3:00)".

If that’s what you mean, the title also makes no sense at all. If you actually mean its sorting, the description doesn’t match the title anyway.

Edit: I had a closer look at the description, no - IV comes before V, not after V. IV is 4, V is 5.

This is a duplicate of MC-269356.

Can confirm in 1.20.2. Since it’s still unresolved, I assume it’s also a thing on 1.20.2-.4.

I lost my old "3A 'n 2A Kids" account so I’m gonna comment here.

Do you mind if you transfer the ownership back to this account? I've had a look at the files, could also add some more description to the bug.

Thanks!
