Dear developer,

I am using version 1.1.99-1.16.1-release, and I get the following crash:

java.lang.IllegalArgumentException: Invalid Line: Point [422.000000, 90.000000]: Point [421.174150, 89.506665]! Lenght: 0.000000.

This does only happen occasionally in my mostly vanilla 1.16.1 world.
If you need more information, I will try to help.

Very strange... Here can't be zero. It looks like some glitch. What java version do you use?

Any way, I know how to fix it.
