I have a custom modpack (Dragon Claw Adventures 1) for MC Fabroc 1.19.2 running on a dedicated server, and for the longest time, I had no idea why this mod was not doing what it was supposed to.

After enchanting a few items, I noticed I did not encounter the issue in my test world, and then I realized, that when spawning in weapons and armor, they don't receive a random modifier (common, uncommon, rare, etc.), and sure enough, this was breaking the Adaptive Tooltips functionality.

If you disable the client setting "Tiered Tooltip" in Tiered config, the issue is resolved, and text wrapping happens normally.
