crash-2020-07-18_16.52.41-server.txt

Can you please https://hatebin.com/ it please. Im not going to download files

im not sure how to use it im sorry https://hatebin.com/zukzajtorc i hope thats right

Im not sure how exactly this Is BYG's issue, looks like a mod is using Mixin in world and it's corrupting fluid blocks?
"at net.minecraft.world.World.func_180501_a(World.java:177) ~[?:?] {re:mixin,pl:accesstransformer:B,re:classloading,pl:accesstransformer:B,pl:mixin:APP:mixins.stevekung's_lib.json:MixinWorld,pl:mixin:A}"

Doesn't seem to be a byg issue but rather a poorly done mixin. Open this issue again if the issue persists
