Mixin errors with BYG (?)

[LiskoSlayer63]

Noticed that you are the same creator for Upstream and BYG, right?

I noticed this in the server console:

I firstly thought that it was BYG's error, but some Googling took me to Potion-Studios/BYG#520 and there you were mentioned that this is Upstreams problem. However, there appears not to be any issues opened here about the situation, so now here is.

I am also experiencing this issue

[criscky]

idk what that can imply, but it seems that file was removed from oh biomes you go in here
Potion-Studios/BYG@0f77058
but it's still being "used" in here in upstreams
https://github.com/CorgiTaco/Upstream/blob/7411217735f8a3be2a45268762835b2df6578208/build.gradle#L96

even tho this file exist
https://github.com/CorgiTaco/Upstream/blob/Forge-1.16.X/src/main/java/corgitaco/upstream/mixin/MixinConnector.java
maybe it's referencing the wrong file?

[DaemonUmbra]

That file was no longer required in BYG and was only referenced in Upstream because of a copy/paste blunder from when it was required

Rant

The solution is to simply delete one line in build.gradle and I have brought this up with CorgiTaco before and they refuse to "fix what isn't broken" even though it is broken it's just that Mixin is happily swallowing the error with a bit of log spam instead of crashing the game.
