I can confirm this as an issue as I discovered and am having the same problem while I was prepping a mod pack for a private server for me and my friends to grind our teeth on. It happened repetatively when I tried to cut Reed with a knife, using any (left, right, shift, or ctrl) clicks to interact. Always with a knife in hand, type didn't matter. Below is my variant of the crash. I did try pulling a few file like dry grass, wildcraft, necessaries, cralutweaks just to see if it was one of them, and the crash was consistent. I am really looking forward to a 1.17 server, but you mod is one of our core challenge mods (Farming tweaks, single harvest, proper food prep and storage) we have always used, so any help or updates for this issue and we would be immensly grateful!
