I have put together a couple of mods for myself including Quark and another mod called Diagonal Fences made by Fuzs.

As of the minecraft version, mod loader and versions here are the details:

Minecraft 1.19.2
Forge v43.2.3
Diagonal Fences v4.2.5
Quark v3.4-405

It doesn't break the game, it just outputs in the log file this following warning:
[Render thread/WARN]: Unable to resolve texture due to reference chain particle->particle in quark:block/template/custom_fence_post

When I say a lot of lines, I mean it. For example in the latest log file I got 1316 lines of this.

Now I don't think it is an actual problem, everything does work, I tested it with Bamboo fences as an example, I just think it wastes time and memory trying to do something.

I just made this to let you know in case you want to take action about it or not, it's fine either way from me. I will also post this on Diagonal Fences github

Looks like a dupe of #4347. This is already fixed, update your Quark.
