Minecraft opens fine and I can play normally until I hover over a tool in my inventory, which causes the game to crash instantly. Non-tool items seem to be fine (ie ones that do not show a 3D preview of the item) Attached are 4 crash reports all caused by Legendary Tooltips (or possibly iceberg, but it is definitely an interaction between the two mods are both are mentioned) each time a variable was changed (turning off CIT visual enchantments, using an older version of Forge Config API Port, updating Quilted Fabric)

Please see #62. I don't currently support Quilt with my mods, since Quilt does not fully support the Fabric API that I am using. Hopefully Quilt will add support for the API calls my mods use soon.

Quilt Loader dev here--You're not using Fabric APIs, you're using internal implementation details. We don't promise support for these APIs, and neither does Fabric--they could break it at any time.

However, I think I was able to add support to what I saw you using in the crash report--you can try Quilt Loader 0.19.0-beta.12.

Didn't seem to fix it, seems to be crashing more or less the same, although it's now referencing sodium in the crash report (see attached). Thanks for trying to fix this so quickly, no worries if you guys can't fix this.

and after some choice messaging from a Quilt developer I no longer plan to.

What?
I have merely stated that the usage of Fabric internal methods are not supported either by Fabric nor Quilt, and such methods can break at any time on Fabric too. This was a good faith warning, I was in no case aggressive, just informative.

I should be able to fix this problem in the next Iceberg update, so look for version 1.1.9 soon. However, keep in mind that I do not support Quilt with any of my mods, and after some choice messaging from a Quilt developer I no longer plan to. My mods are not marked as Quilt-compatible on CurseForge nor Modrinth for that reason.
