Description

Hi. I am coming back to the previously issued bug by another user involving NotEnoughIDs and Optimizations and Tweaks' enableMixinAnvilChunkLoader config option. My situation is slightly different now: I use Optimizations and Tweaks version 1.14.4, FalsePatternLib version 1.4.7, UniMixins version 0.1.19 and NotEnoughIDs version 1.4.3.4, when I enable the enableMixinAnvilChunkLoader config option my terrain gets really messed up like on the picture instead of just Minecraft crashing:

And when I am saying terrain, I really mean terrain. These are not chunks that are not loaded, they are physically missing there and it cannot be changed. I can literally build in this void. The only thing that is generated sometimes in these blank chunks are structures, like mineshafts for the most part and they are the only thing that will keep you from falling down.
In the same time it says that I should never disable this option in the config file, but the problem obligates me to do the opposite, because enabling this option causes me bigger troubles than disabling it in my situation. It doesn't mean that I doubt your caution, I want to keep my game healthy and eliminate any issues that can damage it. That's why I want to ask you to fix my terrain generation problem caused by this enableMixinAnvilChunkLoader thing, so that I could keep it on and have no problems like I've got now and like the ones that may occur by disabling the option. Thank you.

I am assuming this issue stems from this mod's extensive and aggressive use of overwrites which trample over other mod's mixins, and/or locks other mod's code to older iterations of some functions. It was only a matter of time before this hasty method of mixin-ing had damaging effects on worlds.
