my render distance has goten stuck at 18 idk why or how but every time i got into my video settings and change render distance it will say it has changed and the world will reload but then if i exit the video settings and re enter the video settings it will go back to 18 render distance ¯_(ツ)_/¯

I'm having the same issue. Couldn't find any fix so hopefully the dev fixes this one soon as bobby mod is literally a must have mod for me. Sadly I've just disabled the mod for now. Are you using the 1.21 version of the mod? I am and am wondering if its just a version specific thing.

Edit: Just realised I've disabled the mod and it's still happening? Is it a fabric issues instead? I've deleted the config files too, it's strange. If you did fix the issue please let me know.
