Version Info - 1.12.2 - Mods List

[Default]: Minecraft, Minecraft Coder Pack, Forge Mod Loader, Minecraft Forge.
[Added]: Additional Lantern, SuperMartijn642's Core Lib.

Description of The Bug

In 1.12.2, the Lanterns', Chains', and mod's names do not work properly in the Creative Mode Inventory and in the toolbox.
[Exception]: Oddly enough, F3 displays their names correctly.

Steps to Reproduce

Install the mod inside a 1.12.2 CurseForge Modpack, enter a world of choice, and simply browse through the Creative Mode Inventory.

What version of Additional Lanterns are you using?

I'm using version 1.0.1 [additionallanterns-1.0.1-mc1.12.jar] [Uploaded: 4/20/2022]. It's the latest version available for 1.12.2.

I forgot to mention that I already tried this mod on two separate modpacks, with the same results, so there doesn't seem to be any mods causing conflict, nor would reinstalling it change the outcome.

[Update]:

I downgraded to version 1.0.0 [additionallanterns-1.0.0-mc1.12.jar] [Uploaded: 7/11/2021]. The mod works as intended in this version. Odd...

Seems I simply forget to rename the translations file from 'en_US.lang' to 'en_us.lang' when I updated the pack.mcmeta's pack_format.
Luckily it only affects 1.12. Still weird noone reported it until now.

Anyways, it is fixed now in Additional Lanterns 1.0.1a for Minecraft 1.12.
Thank you for reporting the issue!
