not sure if more explanation is needed. when I try to start the game on 1.21.1 I get an error that this mod does not support this version

Are you stupid? Please learn how to read. It literally states that mod is not supported on this version

yes I understood that part, and if work is being done to port it to the newest version great, but since I hadn't seen any other issue about it I thought it wouldn't hurt to say. I'm not used to commenting on github stuff, but if it means I'll just get yelled at I won't bother again. I'd just like to use this mod, I'm sorry if I offended or angered someone with my comment.

It's okay. Mod is being rewritten and ported to newer version, so there won't be any more updates at this point
