Hello, we have constructed a custom modpack and currently experiencing an issue where our server crashes everytime a wood spruce post is crafted. If you could identify the issue or find a work around, that would be great.

Doesn't seem like a quark issue, looks like it's from the shadows.fastsuite mod, I'm not sure what mod that is.
