With this mod installed, some flower from vanilla, this mod and other mods which give purple or magenta (May be also some other dyes) will give suspicious stew instead. I tried to fix this with CraftTweaker, but it's didn't work
Purple Primrose from this mod

Allium

and others (more than this, these're just some of them)

It's a known issue with the suspicious stew recipe, you can disable fern fiddleheads in the config to fix this for now.
I've been busy lately, but I want to finish the release version soon, just need to draw a couple more textures and I'll be ready to fix all the bugs.

Please try Cuneiform 1.3.4, it should fix the issue!
