this mod is the worst mod in the pack, please find an alternative with a config where you can blacklist certain items, or plants or otherwise from "swinging through grass" because sometimes, such as, when i have a mob farm and a bunch of animals on vines or otherwise to reduce lag from entity collisions, it can be quite annoying to move or change the farm in any way because their is a bunch of creatures on vines or otherwise. i find this rather frustrating and i would prefer if i could just uninstall the mod because i have never once in my life had the problem of "i can't hit mob behind grass" however I'm playing on a server and, just disabling the mod client side, does not fix the issue
something as simple as "any shear type" ignoring clean swing through grass effect would completely solve the issue
