Hello, as there are already a slew of other mixin-based performance improvements that take some trial and error to work together properly, and since the mod is crashing on startup with the following mods enabled ( see https://paste.ee/p/YBrbi) I wanted to know if you had any familiarity with the following

1. bugtorch

2. coretweaks

3. flying cullers

4. hodgepodge

5. mixingasm

All these project are on github (except for astrotib's flying cullers, which is currently on gitlab), but I can provide links if needed.
All these mods do work together, but I am aware that each new mixin-based edit brings a slew of problems since they're developed by different people working on different projects with no particular inter-mod compatibility except for some of them (mixingasm itself being a forced compat mod for several other mixin mods).

Thank you in advance for any help on the subject.

I've found the problem, the 1.2.7 jar on curseforge was missing some files because of a local issue in my build server, the one from the github release should work properly. (broken: 27.7kb good: 28.8kb).
I've marked the current curseforge 1.2.7 release as broken, and uploaded the jar build by the github workflow instead.
