LiquidBounce and 5zig are both very big modifications.
There is a high probability that they will interfere with each other, which can lead to bugs or crashes.
There is little we can do about that.
If I remember correctly, the old 5zig version worked well with LiquidBounce.
Thats cause its a "global" shader, every entity gets the same shader with the same color. The implementation of the shader-esp has no support for multiple colors.
It was my custom build like a month ago, I haven't modified any KillAura's related code, I'll try that on the newest B73 nightly build.
Edit: The latest nightly build 7672ffa have the same behavior.
