Incompatibility with either Alfheim, Red Core or Mixin Booter

[DainXOR]

Using the 3 mods:

• When using MixinBooter 7.0 it crashes with error code 1 and no VanillaFix crash report is shown.
• When using MixinBooter 8.8 it crashes with VanillaFix screen but the mod is 'Unknown'.
• Also, using various mods (around 150 in my case), plus the 3 on the title, it just never starts the game, no crash, nothing, not even a window or a process on the task manager, and when trying to starting it again it warns about the game already being open. Killing the launcher from the task manager gets rid of the warning.

Using only MixinBooter:
Finally, before using Alfheim and Red Core, there was an issue using MixinBooter (version 8.8), it happens to behave the same as the third case described when using the 3 mods, no game window, no process on task manager and warning as if I had another instance of the game open.

Alfheim 1.2
Red Core 1.7-1.12-0.5.1
MixinBooter 8.8

I'm also having the same issue, went through logs and VF appears to be the issue for me as well.

If you have CensoredASM then thats crashing it. CensoredASM is not compatible with VanillaFIX

I found that MixinBooster 4.2 works.
