I use:
Forge 1.20.1 - 47.4.2 (With Sinytra Connector)
Obscure Tooltips 2.2 (https://www.curseforge.com/minecraft/mc-mods/obscure-tooltips)
Numismatic Overhaul 0.2.15

The problem is that after installing your mod, the icons of objects from the tips simply disappeared. Obscure Tooltips changes the tooltips in the game, but when your mod is installed, they stop working correctly. An example in the photo, I hovered over the object, then its icon is not displayed.

I believe this is something that Obscure Tooltips need to fix. Seeing as they haven't released any updates in a few years, as well as being All Rights Reserved with a non-public issue tracker, I don't think it will be fixed
