Platzdarm

But how do I update from 1.16.1. I have not found things to copy and paste into the file. for Line 28 and 90'something

People still work on 1.15.2? Why don't they update when they encounter the same problem.

K, thanks will try

I am using 1.16.1 And about the redownloading thing, it is a last resort so I will find out how to do it later.

What do you mean "Update the latest minor"? And by redownloading I mean make a new Mod file and moving/ copy & pasting all the code/images.
