When there is no key binded to comparing hovered equipment, error messages appear in logs every time any tooltip appears on the screen.

These errors do not affect the game in any way. It is just the logs become full of these messages.

Here I run Minecraft 1.21.1 with NeoForge 21.1.197. The installed mods are:

• Apotheosis [8.3.6]
• Apothic Attributes [2.9.0]
• Apothic Enchanting [1.4.4]
• Apothic Spawners [1.3.2]
• Patchouli [1.21-88-NEOFORGE]
• Placebo [9.9.0]

Under these conditions, I have managed to reproduce the same problem from the issue #1587, because there appears a tooltip that shows the exact name for the folder of a new world. But this problem also appears when hovering over many things in the game, such as items in inventory or buttons in the settings.

The workaround to this problem is binding any key to compare hovered equipment.
